Chevrolet - Lumina :: 1996 - Compressor Clutch Does Not Engage And Fans Do Not Spin When AC Turned On
Jun 1, 2015
I am having trouble with my air conditioning system in my 1996 Chevy Lumina. When I turn on the AC, the compressor clutch does not engage and the fans do not spin. I was able to jump the compressor so the clutch engaged, however, the fans still did not spin and the AC was not cold. I then jumped the low pressure cycling switch (near the accumulator), which caused the fans to spin while the compressor was running. However, this still did not produce cold air from the AC and none of the AC lines were cold to the touch. I am starting to think the system is low on Freon, but I do not have gauges to test the pressure.

99 lumina. Ac was not working. I added a few oz's and the compressor clicked on but cooling fans were not running. After 10 min of idling the fans did come on but went off after 1-2 minutes. It seemed like they were responding to coolant temp more than ac pressure. Do the fans run when the hi pressure rises to a certain point where the computer will turn on fans?

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?

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??

Compressor does not engage, and my fans do not come on when I turn on the A/C. They do come on low speed when I jumper pins 1 and 2 on the temp switch plug, but they do not come on high speed when I jumper pins 2 and 3.
I have replaced the FCM with a new one, as well as a guaranteed working used one; neither one changed anything. I assumed right away that it was the fcm because my original one has a hole eaten through it from battery acid.
Compressor clutch ohms out within spec, and it will engage if jumpered.

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?

My daughter has a 2003 Saturn Vue 2.2 and it seems that the clutch if froze up... I have checked Freon level with a gauge that I use to top of Freon and seems ok... the vehicle has 170,000 thousand miles... are these compressors prone to failure and is there a "Quick Fix" without replacing compressor, orphis tube and dryer?

if the fan doesn't work, could this make the AC compressor clutch not engage? I think the fan is burned out because it doesn't spin at all, and only moves with a lot of effort. If the fan circuit is open, will this cause the Compressor to not work as well? the car is a 1991 740 GL. 2.3L engine, non turbo.

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?

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?

So I have a 1996 Chevy Lumina (3.1L V6 engine) and I keep getting a DTC code P0101, which is a Mass Airflow Sensor malfunction. It's rather annoying because every time this happens, my engine shuts off. I'm talking no power steering, no power breaks, no acceleration, nothing. So I replaced the mass airflow sensor and it continues to stop about every five minutes. However, it does something odd and that is that the car drives just fine when it's in Overdrive and stops when it's in regular drive. I don't know if that's important, but I thought it might diagnose the problem.

I got a 2003 GTI 1.8t and the AC air is blowing warm. With the car on, AC on and fans full blast both rad fans turn on but compressor clutch does not engage. Took it to a shop and the mechanic said the system was full of refrigerant but that the compressor was not getting the proper signal and there was an electrical problem.
I check the power at the compressor and it is reading about 7 volts, which is low correct? That should be getting 12-13 volts correct? I also check the pressure switch over by the passenger side and it was getting 13v. What to check next to start ruling out causes? Any quick way to determine whether this is electrical or a compressor issue? I am limited in my abilities as far as electrical work goes.

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.

Sometimes in the morning the AC will work just fine, but after a while it stops working. It looks like the clutch will not engage and I don't know how to troubleshoot it. I'll take a picture later on today. I'm wondering which part is what, and what might be causing the problem.

I have recently bought a R32 2008, and when trying to turn the AC I don't hear the AC compressor clutch clicking, the fans are running normally (radiator fans ). What should I check ? Someone told me that maybe it's a compressor problem, and another one said that if the refrigerant gas is low the clutch won't be engaged.

I'm using a compressor clutch kit to try and pull off the compressor clutch plate from my '96 LT1. Using the tools I got the clutch plate almost all the way off but then it stalled. I've broken every one of the remover screws trying to get it off the last bit. I'm considering picking up a 3 jaw puller to get the job done.

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.

I have a 96 Impala SS with over 100k. I have a problem with it not starting, it is random as far as time of the day or if its been doing it, I will crank the key and it does nothing, all lights are on but the starter does not engage. I tried moving the shift lever and no luck, until I put it in neutral rock it back and toward and then it will start, I've done this three times in a row and it has started each one.

I think my fan module might be bad because neither of my fans spin anymore, and my air conditioning doesn't work either. My buddy let me borrow a fan module but it isn't the right one, I just need a picture of the connectors or a part number would be good too.
