I have a F150, 97, 4.6L. I changed my Suspension belt, and now my A/C compressor is not engaging. This has happened before, and when I took it to the shop, they called me and said the A/C works just fine. They did not tell me why the A/C stopped engaging or what they did. I tried to locate a relay fuse, but I can't find it.

I have a 01 f150 4.2L and a while ago the ac compressor clutch broke. I didn't catch it in time and the stress it caused on the belt broke the power steering pump pulley. So I replaced the steering pump and pulley and the compressor the accumulator/dryer and the office tube put the 134a back in and everything worked fine. three months later ac stopped working. I figured the condenser was bad so i replaced it. Charged it up still no cold ac. so i thought maybe the manifold that goes on the compressor was clogged so i replaced it. While I did that i said to myself well i should tear out the dash and replace the evap as well. so just about everything has been replaced on the ac system.
Aside from the cycle switch and the high side switch witch from my test both seem to be working. now here is the thing. the tube witch holds the office gets ice cold then goes to the evap but the suction line coming from the evap doesn't get cold and the ac blows warm air. this very problem is what convinced me that the evap was clogged and needed to be changed witch is why i undertook the task of tearing the dash out. in all it took 14 hours to do the whole job. now for the pressures that i get from the ac manifold low side goes 40 down to 20 ..... this is normal. high side is a little high. I charge it to 125 still no cold air. so i dump a little more 134 in. at 90 degrees high side pressure should be around 200ish i get it there still no cold air. I have just about replaced everything i can think of.

Got in my truck this morning and everything worked fine, no problems. Arrived at my destination and parked. Come out about two hours later start the truck and my A/C wont blow air, My truck is an 05 lariat so it has the climate control A/C. Everything was working fine it just wont blow air, When i turned the A/C on and off i could hear/feel the small thump of the clutch engaging on the compressor. I am thinking the blower fan just went south? or maybe something stupid that controls the blower fan? Summer is in full swing here in central florida, temps are 95+ not including the humidity...

l have a 2000 model accent and the air conditioner compressor clutch is not engaging . you press the 'AC 'button and the indicator comes on when a fan speed is selected which l am sure is the correct operation.l checked for 12 volts at the coil terminals of the relay and there is no 12 volts.l shorted the switch contacts of AC relay and the compressor did engage so the wiring from the relay base to the the compressor clutch is ok. l also checked the contacts of the 'AC' switch itself and it seems to be ok. l haven't had much luck with sorting out the wiring from the switch to the relay as l do not have a wiring diagram.

I recently purchased a 2005 Monte Carlo, it has the 3.4l V6. I live in Pa. and like others our winter has been real cold, I was waiting to pick up my wife from work the other day, while sitting in the car i was changing the heat selections from defrost to floor to bi-level and realized that the A/C compressor clutch is engaging when the selector is on defrost and floor, it disengages on bi-level. I know that it is supposed to engage on defrost. Is it normal for this car to activate the A/C on floor? if so it is a first for me.

I have a 2000 chevy malibu that has not had a/c the past 2 summers. I'm trying to diagnose what the problem could be. When I start the car and then turn on the a/c by pressing the button in the car nothing seems to happen.
When I went to look at the compressor motor I could see that the clutch is not engage and the middle of the compressor is not turning. What to check without taking to a mechanic??

I have a 2003 ford ranger xlt 4.0L and here recently my ac compressor has been making a loud click noise engaging even though i am not using heat or AC, so when it engages the rpms drop and almost wants to stall and it does this in about 10-15 sec. intervals, but when I am driving it acts fine. What is going on here, I recently had a vacuum leak and i found it and fixed it, and now this issue just started.

Odd question, but the a/c clutch has always engaged randomly even though the a/c is not on and even now when the heat is on. Is this normal?

So that's what if feels like, in park at idle it sounds great, starts great no codes. IF you floor it it will not go over 3000 rpms in park, it feels like it has hit a rev limiter. I have 60psi fuel pressure at idle and at 3000 rpm.
When driving down the road I won't go over 55 mph and drives normal if you keep it under 3000 rpm, if you give it more gas it falls on its face?
AC is not working (clutch not engaging)I don't know if that's related or not.
We did just swap the motor the truck is a 2003 2wd drive. motor came out of an 2002 4wd. we are running the 2wd harness, computer egr delete etc.

Troubleshooting the not working A/C in my 1997 Ford E350 Motorhome Chassis.
1. Compressor clutch spins freely
2. Started vehicle and turned on A/C, clutch not engaging
3. Unplugged Compressor clutch plug, and engine would turn over but not start
4. Replugged, started engine (normal), and when I unplugged the compressor clutch plug, the engine immediately cut-out.
Is this normal? I was planning to check if I had 12v at the compressor plug. Did I miss something? It is almost as if the clutch is wired into the ignition circuit...

My 97 regal has a noise from the compressor clutch. It goes away when the a/c is turned on. Mechanic said its the clutch assembly. Is this easy to change? What causes the noise to go away when the a/c is turned on?

A couple of years ago I went through the salt water with my 2003 Honda Accord which is a manual transmission. It only has 106,000 miles and expects it to go much further. The clutch works great but when engaged is really loud. I have had it checked by 2 different auto repair places. Nothing is wrong they say. It has been cleaned and greased.

2003 V10.. Can I replace the AC compressor clutch with out pulling the compressor out?

I am having a problem with my 1998 F150 4x4. The 4WD is not engaging. It is a manual shift. I have checked the transfer case by turning the drive shaft in 2WD it is free. When I shift into 4WD it is does not spin freely. So I believe that is OK. I have checked the vaccum diaphram. It will move the piston when I attach a hose and pull vacuum on the inboard hose barb. So I believe the diaphram it self is OK. I am not sure if the hoses and selenoids are OK. They look fine. However there is a constant vacuum on the inboard hose line (red/pink color) wether I am in 4WD or not. Is this OK? How can I check the selenoids. If all this is OK, the next thing I believ it could be is the shift fork in the differential. Is that a difficult job? Do you need to pull the whole axle out to replace it?

03 F150 2WD-I dropped tranny pan, changed filter, reassembled, put in 4 qts fluid. Checked dipstick, seemed to be overfilled, despite instructions to add 5 qts. Started truck, put it in reverse, went about 4 feet and then tranny wouldn't engage-ran it through all gears, just acts like in park or neutral. Over or Under filled???

Found out the hard way that the 4wd does not work on this new stupid truck. I've been troubleshooting the solenoids and confirmed that the 2wd solenoid gets grounded and will read ~12V when switched to 4wd; however, the 2wd solenoid always remains grounded and will always read 12V across the plug no matter if it's in 2wd,4hi,4lo. What would cause this? It seems that I would have vacuum going to the front differential from both the 2wd and 4wd solenoids at the same time, thus not allowing it to go into 4wd. BTW, this is on a '98, 4.6, turn dial 4wd

I was out on the lake last night and after getting stuck in 6" of hard packed snow, I discovered that my 4WD is not engaging. When engaging 4WD, I do hear 2 clicks several seconds apart. I've checked the lines from the solenoids to the actuator and did not find any cracks. I have not checked the lines for vacuum yet but...
Last winter while engaging 4WD, I heard a load POP from the front end when I was turning the wheel and engaging 4WD. Ever since then, I haven't been sure if its been engaging but it was confirmed yesterday on the lake. Based on what I've read, I assume its either the actuator or the shift fork. Is it possible to remove the actuator and test it without disassembling the entire front end?
I went under the truck and had my wife engage and disengage the 4WD. The actuator was trying to move (maybe 1/16" inch) but the shift fork wasn't moving. Does this mean the shift fork is bad (frozen) or does this mean the actuator is bad (not enough power to move the fork)?

On 2500 mile trip, no A/C last 400 miles and we're cooking
Compressor clicking on/off about every 5 secs, clutch smell. Seems to be turning okay.
I brought some tools, including a full socket set.
Can I pull the clutch and remove shims in the campground? Looking for a condensed version of how?
Worst case, how do I replace the clutch- of I can find a dealer with one?
Pulley and clutch fixed, but cycling on and off...adding freon?

I have an 06 F350 diesel, I had some work done on it that required the body to be raised on it. After I got it back the A/C didn't blow cold. I put it off for a while since I didn't need it. Anyways, the clutch isn't engaging so the compressor doesn't spin.
Things I have checked: Compressor rotates smoothly by hand. No blown fuses or bad relays (checked them all with meter). No results when jumpering the Hi/low press switches. Tried charging the system and the gage I got with the can goes to 80# and it maxed out. For the air gap on the clutch/shim idea, I tried pushing in on the clutch while it was running with a long extension to see if I could get it to engage, no luck

I have a 2000 F-150 4x4 and the four wheel drive isn't working properly. It does work,but to get it to engage I had to drive in reverse for a couple feet then it locked it and everything was fine,pretty sure that isn't normal. What could be wrong with it? As soon as I turn the lights up on the dash,but the front tires don't spin.
