The ac compressor clutch does stay on

We recently replaced the ac compressor in our 1995 chevy suburban and the compressor keep cycling off and on and will not cool. The AC actually works worse after we replaced the compressor.

Hello narto7
If you replaced the compressor yourself and tried to charge the system with those booster cans from the parts store, then air and moisture remained in the system. This will prevent you from getting the correct
charge and the correct pressure in the system. This can cause the lowpressure cutoff (on the accumulator right side of firewall) or depending on how much R134 was put in) the high pressure cutoff (on the compressor) to cut power to the compressor clutch assy. If this is
the case, have the system evacuated and charged with the proper
equipment and that should clear it up. However if it was charged properly, check the 2 cutoff switch's I mentioned. There should be power in and power out on both with the a/c on. There is also a relay
for the a/c you can check. But due to the split year in 95 it's located in
1 of 2 places, in the fuse relay block under the hood or under the right
side of the dash above the glove box. Remove the box for easier access. Hope this helps

97 chevy suburban AC clutch won't engage pressures


Looks like the low pressure switch gets power from a 10amp ac fuse. Power then goes to the ac relay which is powered on by the ac heat controller on the dash. Power then goes thru the high pressure switch to the compressor. The ac relay is grounded to the body. Do you have power on the lite and dark green wires going into the relay and is it grounded ?

AC Compressor squeals when ac is running. Do i have to replace entire compressor or can you just change the bearing?


most likely the squeal is actually the compressor clutch u may be able to get an aftermarket clutch but it requires special tools to remove and install and u would still have to remove the compressor for the little bit of price difference i would replace the compressor and the belt

I have 2002 Chevy s10 with ac issues. All blend doors and actuators work properly. Clutch engages on compressor. Blows warm air when ac is on. When I put a guage on it the psI stays on max and doesn't...


Yes. When you turn on the compressor via clutch Suction line pressures at around 3000 rpm should be around 30 PSI. If pressure stays high it is because the compressor is running but it is not doing squat and needs replacement - bad reed valves.

I tried to charge the air conditioner on 95 suburban. it doesn't act like it wants to charge. the compressor keeps cycling on and off so can't get a good read on the pressure.


The system could be low on oil. The compressor will shut itself down if it detects a lack of oil or refrigerant. Try adding compressor oil (comes in a can similar to the R-134A) to see if the compressor will stay engaged long enough to accept a charge. It's also possible that the system has so much air in it that it needs to be evacuated before refrigerant can be added. I'd try to add the oil and see if you have better sucess adding refrigerant REMINDER: Have AC on HIGH when adding refrigerant with car running

Hope this helps with your AC problem. Please post back with any other questions. Best of luck.

1999 Chevy Tahoe AC compressor cycles on and off.


That would be the fan clutch on the compressor itself... if it wont take a charge with all setting on high and running then you'll need to get it replaced , have a specialist inspect it to make sure the innards of the compresor arent junk...I have same pronblem with my 97 z28.. but it will take a charge and last 3 months then i have to recharge...The clutch and innards of my compressor are going bad..So its a chevy known issue,,,best of luck...Ohh one more thing do you hear a hiss when you turn it off and on, the ac that is

A/C Cluth not working-replaced Cycling Switch already


the system has a definite leak and should be fixed then the system should be recharged there is a pressure switch that keeps the clutch from engaging when the system is low on freon which keeps from burning up the compressor

Hi,First check the ac relay in the power distribution box under hood.If it is good, with the ac on take the electrical plug loose from the compressor.Check for voltage to the plug.If there is none,verify you have a full charge of refrigerant.If you do,take the ac clutch cycling switch( low pressure switch ) plug loose.The switch should be mounted on the drier/accumulator or near it on low pressure side.Put a paper clip in the end of plug to jump it over.If the compressor comes on replace the switch.Good Luck!!!
