Question about 1995 Chevrolet C1500

2 Answers

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.

    no i don't see one. I haven't had the truck long so not sure how it worked last year. when i start it and turn on the air the center of the fly wheel on the compressor turns then shuts off after 2-3 seconds. this causes the guage on the freeone can i am using to drop way low, then when it kicks off and stops spinning the pressure shoots back up on the gauge. i tried to shoot a little freeone in the line but it started to squirt a little out of the hose coupling.

  • ostate23 Jun 16, 2009

    No i just got a can of recharge freeone from walmart to put in it since it wasn't blowing cold and i could here the compressor coming on. figured it was just low on freeone.

  • ostate23 Jun 16, 2009

    ok the kind I got has oil and leak sealer in it. should i get a can of just oil then and try that?

  • ostate23 Jun 16, 2009

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.

    Yes, I'd get the oil by itself. If the system won't accept a normal charge, it can't get the oil from the can you're trying to add.

    Any brand specified for R134A AC systems should work. There are some with the UV dye in them that cost more but you already have that in the refrigerant so I wouldn't bother with those. I've also come across a web page with some useful information you might like to see.

When air conditioner is on, and the car is idling the rpms spike


You most likely have an AC compressor that is cycling on and off to often, this causes the RPMs at idle to fluctuate. The rapid cycling of the AC compressor is caused by a low AC system charge of refrigerant due to a leak in most likely the compressor shaft seal. Please have an AC repair ship confirm this educated guess..

When stopped in drive the steering wheel vibrates a lot when the air conditioner is on .There are already new motor mounts replaced could it be the adjustment of the idle screw ?throttle plate cleaning...


The belt tensioner can cause many of these problems, sometimes the serpentine or fan belt is replaced, but the tensioner is not given much thought, a tensioner that is going out, can cause the belt to not have enough tension to keep the battery charged by slipping, when the clutch on the ac compressor cycles on and off, if the tensioner is to loose, or not tight enough can cause the compressor to vibrate, it can cause wear on other parts attached to the belt even cause pre-mature wear on other pulleys. good luck!

My air conditioning began making a rythmic squeaking noise when the AC was on. It has now quit blowing out of the front vents. It works on the feet, defrost vents and in the rear air. What could this be??


  1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

The ac compressor clutch does stay on


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

Air conditioner doesn't run.


it is the low pressure switch trying to save the compressor. the system is low on refrigant. on this ford it should be R-134a all new cars are that refrigant.

If the system isn't cycling on and off every two seconds then the charge is fine, your evaporator may be clogged. It might be more cost efective to send it to the dealer.

Air conditioner works intermittently. Will just stop and start or go off and stay off for a couple days. The air that comes out when it does work is very cold. Any ideas what is wrong?


if you recently had the system recharged they may have over filled the system. The ac system has both a HIGH and a LOW cutoff point to keep from damaging the compressor. If it is cycling the compressor on and off (you should be able to tell this by the ac clutch clicking on and off occasionally. If the pressure on the lines gets too high it will cutoof to prevent blowing the lines, if it gets too low it will stop the compressor from damaging itself. I had overcharged my 90 nissan once and it acted this way, it really acted up especially on very hot days.
