Ford F-150 - 1997-2003 :: A/C Not Blowing As Strong As It Used To
Aug 17, 2012
I have a 2002 F150 V6 Extended Cab Truck. Currently my A/C strength isn't as strong as it used to be. On all settings from low to hi, the strength adjusts from low to high like normal. Heater works on floor and defrost just fine.
I'm trying to figure pin point how to make the air flow stronger. Recently my coworker replaced my freon and recharged my system with a new orfice because the air wasn't as cold as it used to be. Now the air gets down to about 58 degrees (he said it could get colder if we replaced the accumulator which I'd like to do in the future).
Right now though I'm trying to figure out how to get the strength of the air flow to be stronger. My evaporator core has never been cleaned. I've never had my condenser cleaned either.
I opened my glove box and unhooked it from the hinges to look behind it, and I found a plastic store bag in the back. I removed it and I think it improved the air flow to normal strength it used to be. Hopefully it's not a placebo effect.

Purchased 2000 F150 (224000 miles) about a year go cheap for knock around truck. Only gets driven about twice week (20 miles most). Has been running great until recently. Got in the other day went about a mile and notice really strong vibration in steering wheel and dash. First thought about something to do with alignment etc. After a little experimentation realized it was the motor. When you get to around 40 mph and try to hold the speed constant it starts shaking (I believe the motor is missing). If you mash the gas and accelerate it stops. As soon as you try to hold constant speed again it starts again. I can run it up to say 45 and let off the gas and the shaking stops. Once it was driven like this for about 5 miles or so, when I come to stop sign it idles rough. If it is put in neutral runs smoother. Could the fuel filter be clogging up? I did try some additive to see if it would clean it out, no luck. Now the check engine soon lite came on. Fuel Filter, Plugs?

I have a 97 f150 4.2L 5 Speed that is only blowing hot air. A/C lines are cold when A/C is on, but coming out of vents hot. When I turn the temp selector, on cold the air is warm to hot, but when turned to hot, it gets a lot hotter. Not sure how Fords operate (left my Chevy behind and got a ford). Blend door, thermostat, vacuum line, or actuator? Where to begin? Radiator and cooling system full with no air in lines and no leaks. Hope it's nothing too big.

Why the 30amp PCM fuse located in the under dash panel would blow. Problem started while truck was running and a simple replace of the fuse would it it back alive again. Now fuse is blowing at ignition on. Truck is 1997 F250 LD.

I am having trouble with fuse 23 under the hood blowing while driving. I have read several threads on this issue but still no luck. I have removed all 4 02 sensors and ac relay and still about 1/4 mile down the road the fuse blows, and is giving the shift solenoid A shift solenoid B and the torque converter clutch solenoid electrical circuit. I have checked both plugs on the trans, I even dropped the pan and ohmed the solenoids out. I dont know what else to do?

I have a 97 F-150 that the A/C went from blowing cold to hot instantly. I have done the following;
1. Checked fuse. Was good.
2. Checked Low Pressure connection.
On this, I jumpered the connector and could not get the clutch to engage. I also checked to make sure I had 12v from that point, which I did.
3. Checked the power to the clutch assembly. Got nothing. I also put 12v directly to the clutch and it poped in just fine.
Based on all of this I think I have a bad relay between the low pressure sensor and the clutch assembly. The only problem is I cant find it. Where this relay is located

I have a 1997 F150 4.6 V8 and as we all know these trucks are notorious for the spark plug blowing out. Although when I bought it I never had an issue until we put motorcraft plugs in. After a couple weeks of having these plugs in the porcelain blew out of the plug with the threads still in the head. The spark plug screws into a threaded insert which then screws into the head. We replaced the plug and nearly a month later the porcelain blew again. Replaced it, same story a week and a half later. Before the motorcraft plugs I had autolites in it, and I never had the slightest spark plug blowout problem. Should I just put an autolite in the cylinder that's blowing them?

I took my truck to a friends express lube to have some freon added to it. My truck has been blowing cool air, not cold. So i thought it might be low on freon considering its a 2000 f-150 w/ 145,000 miles. He took a pressure gauge to it and said it is over charged, the pressure was high.

I have a 97 f150 that only blows heat and I am wondering if the blendor is bad or is it something else that is causing the issiue

I just bought a 97 f150 4x4 4.6L v-8 and keep having problems. The check engine light came on saying that it is running too lean. The truck had been sitting for a while so I changed the air filter, maf, and pcv valve. After changing the pcv valve it is now blowing white smoke. What can be causing this to happen?

My 00 f-150 is not blowing air through the heater I replaced heater core and the temp door I had same problem before work done I did not see an issue when apart but no vacuum or electric to test when apart. The only thing that changes when I move selector for vent floor and defrost I do get a little better flow when on vent. My feet get cold and defrost is not working well if I put hand on defrost I feel warm air but 3-4" away when on floor; I feel nothing anything at all fan seems fine.

I have a 97' F150, 4x4, Auto trans, 5.4L Lariat. Power locks and windows. Auto locking hubs. It doesn't appear to have any theft deterrent system installed.
It has been sitting for some time. When I hook up the battery the headlights, dash lights, and wipers turn on and the horn starts blowing continuously.
Cycling the key in the ignition or door has no effect. Cycling the key to the start position does not engage the starter.

98 F150 2wd 5.4 -even though VIN says its "W" 4.6; it has a 5.4 with 4.6 timing setup-found. But that's a whole other story...
So, Replaced heater core. did the blend door too.
A week later it overheated and blew a heater hose off the core at the firewall (several times). Temp was up and down, forced me into cylinder head protect mode, so i called my mechanic.
Mechanic used a sniffer (blue liquid turns yellow) in my overflow tank and there was exhaust gas in it... so we replaced head gaskets, intake, timing, water pump, radiator and the rotted out rad support.
Got it done and back on the road, but a few weeks later and the heater hose quick disconnect blew off again, spewing coolant all over (again). This was what we thought was part of the original problem- head gasket allowing cylinder compression into the coolant passages. the little rubber hose that comes from the back of the intake and goes up into the heater core builds enough pressure to pop the disconnect right off and I dont know why. Like I said- I thought it was the head gasket blowing pressure into it but that's all been replaced. Why the pressure would be so high at that point, and how do I correct this?
This is my daily driver, so for now I've bypassed the heater core, but I'm afraid that pressure is gonna burst a hose and/or fitting again.

I have a 2000 F150 with @175K miles. Replaced the clutch about a year ago, replaced the front calipers a few weeks ago, due to the right front locking up on my way home from work. Since then, when I try to start, it blows the fuel pump fuse. (#10)...

So I pulled into my driveway yesterday about 5 minutes after my low fuel light came on and as I was making the final turn around my house the engine cut off. Luckily I was able to park in it's normal spot before coming to a halt.
Anyway at first I though "out of gas" even though I knew I'd driven further with the light on. After putting in 3 gallons still no luck. I noticed with the key on no noise from the fuel pump so I checked the fuse and relay both were fine. I then checked all the other fuses and noticed the large 30amp PCM fuse under the hood was blown.
When I replaced it, it blew instantly. I was able to hear the fuel pump come on for a brief second before it blew out. Unsure if the two were related I then pulled the Fuel Pump fuse and replaced the PCM fuse one more time and again it blew. The motor cranks over but won't fire (not getting fuel.) Where I can start to correct the issue.

Every thing was working great then the AC quit. I ran through the air selector and all I can get is panel and defrost with no heat. I checked the vacuum line on the passenger side engine compartment and it looks good. Oh I also took the control apart and 3 of the five holes had vacuum to them.

I have an 01 f-150 4.6 triton and it now blows a sometimes pretty big ploom of white smoke at start up. Sometimes it smokes for a while after that and sometimes not. It runs smooth and strong but I have no clue what to do...

2002 F150 5.4L. Keeps blowing fuse in location #30 which is a 30a fuse for the following:
Passive anti theft transceiver
Cluster
Ignition Coils
Powertrain control module relay
Coil on plugs
Radio noise capacitor
ECC diode
Could this be a grounding spark plug wire?

My 2002 f150 blows the overdrive fuse (#29) every time the overdrive tries to engage. Could it be the overdrive switch? Where is that switch? Could it be a speed sensor? Truck has an automatic transmission and a 5.4 engine.

2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

My 01 f150 keeps blowing a fuse. It makes the O.D. light flash, only have 2nd gear, motor runs real bad. I forget how many codes it had but it was a bunch. It doesn't blow the fuse rite away. Sometimes its days between sometimes its hours. Where to start looking for the short?
