Ford - Explorer :: 2002 - Intermittent A/C - Running Cold Then Hot
Jun 1, 2015
Have been having problems with my a/c on my '02 Sport Trac (4x4 w/ 235K miles) running cold, then hot, then cold again but inconsistently. Aside from the fact that it always seems to happen when I'm really in need of some cold air, there doesn't seem to be a pattern...in traffic, idling, highway driving, city driving, but it does seem to be a bigger problem at lower speeds or in traffic. No issues with air flow or controls, just maintaining cold temps. I've already had the system recharged and in the past replaced the a/c manifold hose assembly, and a dye test was inconclusive.

We have a 02 Sport Trac that has intermittent brake light problem. All other functions for the bulb filament for the brake lights work! Turn signal and flashers work great. The brake light that is above the rear window works, BUT the brake lights on the rear of the Sport Trac work when they what to.
Right now I can not find a cause that causes them to not work or to work. This morning they worked in the garage but did not work as my wife pulled out of the driveway. Last night they did not work on part of the way home but worked coming into the drive way.

Have an 02 Explorer XLT that recently had its' ABS light intermittently come on. As well when the ABS light is off the brakes will pulsate when slowing.
Took to dealer they noted the following:
Rear sensor out .... ABS Control unit is out. Was shorted out due to Hydraulic Control Unit going out. Hydraulic control unit is obsolete at Ford.
Questions:
With all of this going on, how was I able to brake although not adequately?
Does the HCU control normal breaking too (without ABS)?
Immediately he says he would not put the money into it and wants to get me to someone to trade it in on another vehicle? While I understand the logic somewhat I do not being approached like this.
Can I get a better quote going to a mom and pop mechanic and getting second hand parts?
Is there a possibility to bypass/disconnect the ABS system and would it be recommended?
How to deal with? Vehicle is in great shape aside from mechanical issues creeping up and don't want to lay out the dough for a new vehicle.

My 2002 Ford Explorer 4L V6 is running rough I found out why I just don't know what the piece is called because I need a replacement. Mine fell off and fell down the engine and melted quite a bit. Also the part number on my piece doesn't work anywhere, that I have typed it in. Mine has a Ford part number of 1L2U-9F764-AC. Also need to know the proper Ford number. I have a picture I found online with an arrow pointing to the piece I need.

I have a 2000 Explorer W/4.0 SOHC engine. With summer nearly over and fall on the way, I need to figure out what is going on with my engine. This problem has been going on for the past 2 years. As the outdoor temperatures get cooler, the harder it is to start and keep the engine running. This starts happening around 65 ambient temperature, and gets worse as the temps drop. By 30, I can barely keep the engine running.
Odd thing is, all I have to do if the engine starts is, keep my foot on the pedal to keep the engine around 2000RPM, put it in gear and start driving. After about a mile or two, the engine runs normally, and will do so the rest of the day. So far I have cleaned the air flow sensor, replaced the IAC, replaced all the injector "O" rings, and cussed a lot. I smoke tested the engine and the only vacuum leak is a very small one at the EGR valve.

On my V8 02 XLT Explorer the engine is running rough like it's missing.
I think a coil may have gone bad,,found a LOT of anti-freeze down in the spark plug hole.
Have replaced the intake but now need to fix the roughness.
Is there any easy way to check each coil? Or should I be checing something else?

My son ran off the road in a neighborhood and hit some large rocks along side the street. It punctured the front right side and obvioulsly damaged the steering because now it drives terribly and instead of the steering wheel handles being side to side it is 90 degrees perpendicular. The service station I use said it has a bent frame and will need to be taken to a body shop. Will the cost to fix it be worth it especially due to its age?

248k miles on it, was taken from a body shop and put on side of road, I know who took it but can't prove it. He is known for messing with ppl vehicles. . Started up just fine when found, but you can hold foot completely down on gas and it's like it is losing pressure (?) , it rumbles and shakes when running and you can watch the RPMS fall while holding gas pedal down (in park) until it just dies. It has an "egg" smell and one side will get hot while the other stays cold. It was something intentionally done to my vehicle. .already checked Cadillac converter and cleaned/removed muffler. I'm not sure where to start looking now, I'm a single mother without the money to take it to a repair shop. We could drive it onto the trailer to get it to a friend house, but barely made it up it without dying...

I have a 2002 Explorer with 147K that makes a chirping sound when I start it and the engine is cold. So far I have replaced the serpentine tension-er and the water pump. After about 10 minutes of running the noise stops. With the belt off the idler pulley spins freely. It does have the original power steering pump.

Have a 2002 Ford Explorer 4.0 6cyl. w/ around 150K
I recently started hearing a little chirping noise when starting from cold. The rate of the chirping increases with the rpms (reving in neutral or when speeding up while driving). The sound usually goes away after things warm up.
Doing some research, the most suggested cause for such chirping is something called a Camshaft Position Sensor. Information mentions that this item can either need lubrication or to be replaced.
I was going to try lubrication first....then if the problem persists...replace.
My biggest issue is locating it on a 2002 4.0 Explorer (4 door, 4wd). I've read different reports for different Year models (mostly 97-2001)...which often include pictures. But I can't find ANY pictures for the 2002 4.0
QUESTION: Where it is located on my 2002 6cyl model? I read one account of it being on top of the driver's side valve cover....and I DO see an item in that location secured by one bolt..and it does have an electrical wiring harness attached....but I'm not sure...and have not seen any photos that look like my engine.
I've attempted to upload a picture of what I think maybe be the sensor (circled on red).
I've also come across an item called a "CRANKshaft position sensor".....are these different items, and, if so, does the crankshaft p.s. also "chirp" when needing lubrication or replacing ?

2002 7.3 running rough.
This is my symptoms : On cold start ups engine runs rough. Idling it knocks worse than normal on the road she runs really rough. If I get on here she smooths out ( but still runs rough a bit) but normal driving at between 1200 -2000 rpm she runs so rough it shakes the whole truck. It will do this until she gets up to operating temp & then it goes away. The more she warms up the better she runs.
Once up to temp she will run perfectly. The colder it is outside the worse it is & the longer it takes for it to go away. I have replaced the valve cover gaskers and new harnesses, new glow plugs. Still same problems. I have AE and one time it gave me a #2 cylinder code. have not been able to repete this code. What to check next.

This is a 2002 4 Cylinder Camry XLE.It gets cold when running down the highway, but at a stop , AC gets warm.I have replace the cabin filer. A couple of years ago, replaced the AC MAG Clutch Relay, when AC light was blinking.But now I feel the condenser in front of the radiator and it feels very hot, and the fans never seem to come on.I can see the 3 Fan relays, and not sure where the ECT sensor is located, or whether that would be the problem.If the fans arent coming on at all, you would think the car would overheat?
Tested the motor on one of the two, with direct 12 volts to it, and it did not run.Tested the disconnected cable that would be supplying voltage to that motor and it read 13+ volts. So I would think it was a bad motor, but I would like to see the voltage on that disconnected motor go to zero, but not sure if that happens, or when?Guy suggested at parts place that sells the Two Motors, Fans, and Shield all as one unit for less than $100, that maybe the motor burned out because it was running all the time.
WHen should the electric motors not be receiving power?I read somewhere that when car starts that both are on low speed, and Always on when AC is on. But do one or both ever turn off? If I pull this shroud out with the two motors and buy the replacement, I just don't want to have the motor blow out, because there is something making it run all of the time.

02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. What's happening here? I'd sure like a functional gauge...

1997 Explorer belonging to a friend who will show up complaining that his battery is dying. Of course, the problem is intermittent.
So far, tried 2 new alternators, (rebuilds), 3 batteries and several diagnostic sessions which have been inconclusive. What I do know is that when the charging system is not working, I still have full battery voltage on the Y/W and LG/R wires on the small wire plug at the alternator. The path from the alternator output through the megafuse to battery + does seem to be intact. Measures full battery voltage and even tried a test by using a battery booster cable to connect the alternator output directly to battery + when the system was not charging.
No change with this test. Visual inspection of the engine to firewall ground strap and the battery - to rad cradle ground wire seem to be OK. Have not had the opportunity to try the jumper cable trick to verify the alternator case to battery - circuit, (darn intermittent!). There did seem to be something intermittent related to a wiggle test in and around the power distribution fuseblock, but once again, this was inconclusive. I also was able to make the charging system fail, (once) by turning on the headlights and blower motor.Any specific failures that may cause this? Not much left to change or check!

A friend of mine has a '93 Explorer 4x4 with an automatic. He's getting an intermittent shake at highway speeds. It shows up every 5-10 minutes or so. Apparently the problem has been going on for a few months now. I took it for a test drive the other day, and it feels similar to driving on rumble strips. It shakes in both 2wd and 4wd, but he says it seems worse in 4wd. The vibration feels more like it's coming through the seat than the steering wheel. The vibration will go away if you take the foot off of the accelerator, or if you pull it down into Drive. He's got about 220K miles on it. The previous owner said the transmission was rebuilt about 30K miles ago, but who knows. He's had it in the shop for a couple of days, and they've checked the usual suspects - u-joints, ball joints, and the sort.

Check Charging System message, battery-shaped idiot light, and audible beep has happened a few times over the past month or so. Yesterday it happened while my wife was driving so I had to bring it to the dealer, not to mention I drove it last night and there was constant beeping for about a minute which was pretty annoying.
But first I had the battery checked, which turned out to be OK. Also we got a new alternator 5 months ago, installed by the dealer.
Today they said they "updated the computer" whatever that means, and otherwise couldn't find anything wrong. $99.85 plus tax.
Needless to say I'm not confident that "updating the computer" has fixed it. What are the odds we get the warning again in a couple of weeks? Short of disconnecting the sensor, is there anything that can be done?

My 2007 Explorer (XLT, V6 4.0L, 4WD, 175k miles) has been experiencing a check engine light, intermittently, for the past few months. I took it to AutoZone to read the code and they gave me a printout for P0193. For awhile, the light would go off after I filled the tank with gas (usually the next day) and would come again as the level in the tank decreased (typically around 1/4 of a tank). Then about two months ago, the behavior seemed erratic and I could no longer predict when it would appear. During the past couple of weeks I only recall seeing the CEL once (briefly); it's mostly been off. Saturday night I was out driving and it came on again.
About two hours later, my vehicle "conked out" on me. It started hesitating (it's been a very long time since I've run out of gas, but that's what it reminded me of). Fortunately, there was no traffic and I was able to get it off the road but didn't have enough momentum to get it into a defined parking space before it quit. I sat there for awhile pondering my options (not too many since it was the middle of the night and I don't have road service). After about 10 mins or so, I decided to see if I could get it started. It did start and I was able to drive it home (< 10 miles). It's been sitting in the driveway since because I'm afraid of getting stranded if I drive it again. BTW, I was low on gas when it died -- about 50 miles to E (was headed to the gas station when it happened, but took it home instead).
After everything I've read the past few days, I'm expecting that I need to replace at least the fuel filter, the fuel rail pressure sensor and the intake gaskets for the manifold. I am not a mechanic, don't have diagnostic tools, my funds are really limited right now and I'm pretty much on my own to figure this out.
Q1: For those who may have some knowledge about this particular issue, does the intermittent nature of the CEL give any clues to which part(s) might be malfunctioning?
Q2: I found a replacement FRPS made by Bosch on Amazon, significantly cheaper -- is this brand ok or should i stick to Motorcraft?
Q3: Any advice on the manifold gasket replacements (is one brand better than another)?
Q4: Do I really need the special tool to replace the fuel filter?
The questions above are no longer relevant. I'm in the process of "locating" the sensor. I have the air hose and throttle body off. Now I'm looking at the EGR valve. It looks like I will have to disconnect the it from the large pipe beneath it. Will I also need to remove the two smaller bolts that mount it to the manifold cover, or can I remove the cover & valve together? It looks like those little buggers are going to be challenging since they are facing the back of the engine compartment. This is rather slow-going for me, but there's no turning back now.

2001 F150 ... I'm having trouble with my truck starting after its been running for awhile and then I shut it off.... I have to let it sit for a few min. Before I can crank it again and it will start. I was driving down the road and it just died on me the other day that's what started all this...
The fuel pump and filter was already replaced and I just replaced the cam and crank sensors ... but its still acting up...... I'm not sure where to turn next... No check engine light ..... I have a scan tool and checked for soft codes but nothing.

Engine revs excessively when I press accelerator to shift between 2 and 3 gear. It acts like the transmission is having problem "up shifting". However I had the transmission checked thoroughly and all checks out OK. New fluid, no leaks, compression good, bands good, no debris in housing etc. This engine rev also occurs while stopped at stop lights for no reason. (no acceleration, etc) I also notice the fan behind the radiator running at high speeds when engine is in idle mode. Fan revs and then slows and then revs again. Don't know if this is related.
Engine rev is not related to running the AC. It happens if AC is on or off. The fan rev and the engine rev are not the same sound or symptom.The vehicle runs fine when I first drive it on 40 mile trip to work in the AM. As the day goes on and the vehicle is driven more then the engine rev problem shows up. (again on an intermittent frequency). Question. Could a dirty fuel filter cause this engine rev. Question. What might be some things to check out to find and resolve this problem?

2003 Ford Explorer 4.6 liter AWD. Having some kind of VERY STUBBORN idle / emission problem. When it started it was an intermittent rough idle, mostly going too low or making a periodic "drumming" sound that could be felt and heard at the air cleaner box. CHeck engine codes were PO 442 evap system leak. I first cleaned and inspected throttle body, mass air flow sensor and idle air control valve. I inspected hoses for leaks, including spraying cleaner to see if I could detect idle changes / leaks. I then replaced Idle Air Control Valve. Did not seem to cure problem . SO took it into Ford Dealership and they smoke tested and said needed Vapor Management Valve and Vent Solenoid. I replaced VMV myself. Idle no longer "rattled" but when driving and braking the idle would drop down very low and sometimes not "kick up" and would die. I then took it back to dealership to have them replace the vent solenoid and reprogram the PCM. Still doing it. They said I might have a defective (new) Idle air control and to replace it- otherwise they dont have a clue.
