Ford A/C :: 2002 - Air Turns Hot After Sometime - Compressor Clutch Disengages Over 1500-1600 RPM?
Oct 23, 2005
I have about 80K miles on my 2002 F-250 P/S. My AC will cool big time when I first turn it on. But, after I have been on the road for a while (20-50 miles), the AC turns hot. I noticed that the compressor clutch disengages when the engine goes over 1500-1600 RPM and when the engine slows back down, the clutch re-engages. I have had:
1. Bugs cleaned from the front.
2. Evacuated and recharged (3 times).
3. Cycling switch replaced.
All these were done by an authorized Ford dealer. But the system still gets cantankerous at cruising speed (1900-2000 RPM).

I've got a problem with my AC Compressor, with the AC on the compressor engages then disengages about every 5 seconds. Now I looked into it and some people said you can remove a washer to remove a gap. Do you think I should change the whole unit? Looked online and I can get one for $100. If I do work on the AC compressor to try and fix it or remove the whole unit do I need to drain any refrigerant etc etc. I have a hayness repair booklet and they said that to remove the ac compressor you need to get it drained by professionals. Although on the compressor I only see a electrical plug and no hoses.

I have a 2002 F250 on which the AC compressor clutch is not cycling: I have checked and added coolant so low pressure is correct (don't have high pressure gauge). I checked the clutch air gap and it is at 0.030 " as specified in another post. I replaced the low pressure AC cycling switch (on the evaporator/dryer). With the AC on, I disconnected the AC cutoff switch and the clutch disengages. This circuit has the correct (>10V) going to it. I am thinking it could have something to do with the AC relay.
When you switch the ATC to a setting other than AC or Max AC, the clutch disengages fine. I noticed this problem because the AC shuts off when it is really hot, after I have been driving for a long while, about 1 hour or more. If you shut off AC, wait a few minutes, then turn on it works fine.

Yesterday my truck began to give me some problems starting. The engine turns over just a couple of times then it sounds like the starter disengages and winds up. it took multiple attempts but it finally fired up. Does this sound like the starter or could it possibly be the starter relay?

I have a 2006 Expedition with 90k miles. I am the original owner. don't drive the vehicle much just mostly when the family goes somewhere or when I'm putting the Jet skis in the lake.
About a year ago the air con went out and since I don't drive it that much I decided to fix it later, well now is later. How to diagnose the AC system. what I am looking for is a methodical step by step procedure for trying to find out what is causing my AC to not work.
the symptoms are, the compressor turns on runs for a few seconds and then turns off. inside the cab I can hear hear a hiss noise during the few seconds that the compressor comes on and fades away slowly when the compressor shuts off.
I bought a can of 134a with the gauge, I adjusted the gauge for the correct ambient temperature hooked up to the low side and was surprised to see that the Freon was only a little low. I topped it off but still no change in the compressor running.
I bought a set of manifold gauges from Harbor Freight (I know I know you get what you pay for) in any case I hooked up the gauges to see what the pressures are when the compressor turns on but only seeing a little change.
Any way I took my Speedy (expedition) to the local auto air conditioner shop the mechanic hooked his gauge set up to the vehicle, watched it for a few minutes, made some phone calls, came back. He did tell me that he was going to have to replace the compressor, condenser, dryer, expansion valves both front and back and flush the rest of the parts that did not get replaced. I suppose this is a good price if all that work really needs to be done???
However I would like to exhaust all of my options before I dump half the vehicles blue book value into the air conditioning. so I've been searching the internet and found that it is possible the problem may reside in a control valve that may be present in the type of scroll compressor that is in the expedition.

My new-to-me '07 Elantra has 109k on it & I'm not sure if the clutch is orig or 2nd. It doesn't slip in any gear, but the actual active section of pedal is really only the bottom 3". If the pedal is not on the floor board It isn't fully disengaged. When letting out the clutch it is effectively fully out after only 2-3" off the floor. With that said the 'free play' is only the very top 1/4-1/2" as it should be.
I've never had a clutch that felt as this one does, & I have 15yrs history driving manuals.
My first thoughts are:
1. clutch disc is almost gone & getting ready to start slipping
2. restrictor valve is clogged
3. slave cylinder is weak & not throwing full range anymore

So I just bought a 2000 MK4 Jetta for a $1000, its been ok, replaced the breaks, rear calipers, swapped in new headlight socket, swapped in amber tails, new plug wires, new drive belt, water pump/ timing belt all new.
Car has 173,xxx and i drive in pretty bad traffic daily, there are times when i am going to accelerate and between 2-3k RPM it feels like the clutch disengages then re-engages for a split second. then continues to drive normal, happens 2nd, 3rd, and 4th. Is this the clutch slipping? will it be fixed if i were to order a new clutch kit? I am on a budget and do all my own work, so i can't afford to buy a new clutch kit and have this not fix the problem.
Also, the car gets a little wiley on the free way, feels like its the struts, but the steering wheel vibrates a bit, i just found out the PO had different rims on the car before. So the tires might need to be balanced. I JUST Ordered new Racelands hopefully to stop the creaking/bounciness of the suspension. How to get this steering in check.

I have a 2005 Suburban 1500 2WD with auto level suspension components. At 9yrs old, the compressor is running very frequently likely indicating a leak in the shocks - I am wondering about replacing the original auto level parts with a conversion kit and installing regular gas shocks instead of the really expensive auto level shocks.

So clutch doesn't engage and compressor is not running. I have 12-13v at the low pressure switch and the same at the high. When I jump the low pressure I don't get any voltage at all at the plug that controls the relay for the clutch.
Where I'm confused is:
Is this a low pressure problem - gauge is reading 60psi on the accumulator
Or
Is this electrical somewhere?

I just picked up a '94 7.3 IDI Turbo, and I can't figure out what ails the AC. It appears that there should be enough refrigerant (according to my recharge kit), but the compressor clutch will not engage. I have checked the fuses, and all are fine. All other HVAC functions are normal. Is there a way to test the compressor?

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.

He has a 96 explorer and his ac compressor clutch was cycling on and off. So he went and bought 2 20 ounce cans of 134a and proceeded to add it to the evaporator service port. Of course a lot of it sprayed out side of it as it did not fit well (duh). So he has no Idea how much he actually got in there out of the 30 or so ounces he dispensed. He is laughing at himself with me on this. He says hi ahead of time
I have access to good gauges and a reclaimer and vacuum as I work sometimes for a residential ac guru. So what to do? I was thinking the evaporator should be changed out but I want a second opinion. Then vacuum and add new 134.

Says A/C Compressor Clutch Circuit open. A/C blows hot air....go to VENT and the EATC controls the temp fine (ambient air only). It's on a '97 Lincoln Mark VIII if it makes any difference. Pulled code # 1530 ...
Clutch does not engage but the compressor does turn. Also the EATC will NOT go into the test mode. Push OFF and Floor at same time, then AUTO within two seconds. Nothing. Is this a clutch gap problem? New clutch was installed about a year ago.

I have a 94 Ranger with 2.3L motor. Last week my ac quit working. I push the in and the ac light goes on, but the compressor clutch won't engage. I changed the relay, but that didn't work. The fan still works, but the ac does not come on. I tried banging on the compressor pulley, but that didn't do anything. The clutch is not frozen -- it spins freely. The connector looks good and I haven't done any work in the engine compartment so I couldn't have accidentally moved any wiring. What I might try or is my compressor simply dead?

I just bought a 96 f250 5.8
Upon driving home, i tried the ac again and the ac clutch started to smoke. I replaced the clutch with one from autozone, but when I tried it again, it made a screaming death noise upon clutch engagement. Is my compressor seized?
I tried to turn the clutch (not the pulley, that spins fine) by tapping one of the slots and bolts with a screwdriver/hammer. It was firmly locked in place. If the compressor was OK, would it have turned easily? If I need to replace the ac pump, who sells a good/cheap/reliable one?

2000 Explorer Sport with 4.0L SOHC engine. When I turn on the A/C the clutch on the compressor cycles off and on every 10-15 seconds. The A/C cools and the gas charge is checked as OK. Is this normal?

The clutch in my ac compressor is not releasing causing it stay on all the time and not cycle and get hot and freeze up the system. Also pulley seems to be angled like it's not sitting straight. Can I just replace the clutch on the front? if so what's all involved. I need to do the entire compressor?

soo a friends 03 f-150 w/ the 4.6 has noticed the a/c compressor clutch engaging while heater is on. clutch engages for about 3 seconds or so and kicks back out consistently but only w/ the heater on. a/c dose function property when using a/c functions... Is this normal or does something need serviced???

The A/C in my truck stopped working last year, and this year I intend to fix it. I believe the problem is with the compressor clutch because it was making noise as it would engage or disengage. It was making this noise for a good year or so, and then one day the noise stopped and I have no A/C. So I am only assuming its the clutch.

On my '92, 302, I have a failing compressor. It is "catching" after 1 - 3 turns. The clutch doesn't want to spin freely, not cooling well at idle and local shop advised me to get a new everything, if I want it to last.
My question is if I can pull a compressor from the JY, from same year/model, replace orifice tube, run a cleaner thru, evacuate the system, and fill with appropriate refrigerant. The reason I'm not doing the full repair with new compressor, new condenser, new drier, is I'm going to be pulling the engine at some point with a newly rebuilt engine I'm working on. I know the old system have R-12, but isn't there a way to just get by with the 134 retrokit's?

I have a 1995 Ford Windstar. When I turn on the air conditioning, the compressor clutch does not engage despite having sufficient refrigerant in the system. Jumping current directly to the compressor clutch will engage the clutch, so it's not the clutch. I suspect the relay for the compressor clutch inside the CCRM may be bad, but am not sure how to test it. I have a Haynes repair manual, but how to test this device?
