1993 S10 Air Conditioner Noise

My '93 S10 (2.8 V6) makes a "rumbling" or very low "whining" noise when the a/c compressor kicks in. Sounds like maybe it's just the heavy load on the smaller engine but other than that no problems with cold air or anything.

Whine noise


Remove the drive belt to the ac compressor and spin the pulley by hand .If it feels rough or can be moved sideways then replace the bearing in the pulley (it can be separated from the compressor with out opening up the system)

93 Diamante making clanking sounds under the hood. From fairly quiet to fairly loud. Sounds like it's coming from the belt area, a/c ciompressor area of the car.


This could be caused by different things. It sounds like it may be your timing belt though. If you remove your drive belts (alternator, power steering and air conditioner belts), and then restart the vehicle, if the noise stops, then spin the pulleys you just removed the belts from, to see which one is making the noise. If the noise does not stop, then it is most likely the timing belt tensioner making all that noise and you will need to have the timing belt and associated parts, idler pulley/s, tensioner, water pump and seals replaced. Hope this helps. Have a nice day :O)

2003 Honda CR-V when the A/c compressor kicks on the engine drops 300 rpm, like it's going to stall. It's making a clunk noise when kicking on and I changed the battery thinking it was weak.


sounds like it's the iacv or idle air control valve not working due to dirt in the orifice or the iacv is burnt out and cannot turn correctly, or the wiring to it is faulty.

Good luck on the repair.

If the A/C compressor makes a clunk noise when kicking on, that could indicate a worn out compressor.

You're right, 300 rpm is way too low. It should be closer to 600 or 700 or 800 rpm and remain smooth when the a/c compressor kicks on.

When I turn on the air conditioner sometimes it makes a chattering noise and continues to make the noise and other times no noise.


Sounds like a problem related to the a/c compressor clutch, or that the freon level is too low, and it is starting to damage the internals of the compressor. If when it works with no noise, it is not cooling the cabin, then the compressor is definitely shot. i have seen in a few instances that taking apart the compressor, cleaning it, and replacing the oil, it reduces or stops the clattering.

2000 Chevy Cavalier making a noise when air is shut off


This problem sounds like the aircompressor pully, the bearing is shot.
With the engine running and the air conditioner off there is a grinding noise, look at the compressor pully, does it wobble? Then turn on the air conditioner and the noise stops, look at the compressor pully again, the wobble stops? If so that's the problem.

I have a loud whining noise coming from my ac compressor. i have a 98 cadillac deville and it makes the whining noise even if the ac is off. it makes that noise the whole time the car is running


The A/C compressor constantly turns because the pulley is connected into the serpentine system. The whining noise is pretty indicative of a low charge in the A/C system. I would start by having your A/C pressure checked and charged if needed.

Low compression cyl has 20 lbs of compression.


A leakdown test is where you remove the spark plug from the problematic cylinder,and install an adapter and air hose,shop air,about 90 to 120 psi.You have to be certain both valves are closed on that cylinder,and i do this by removing the valve cover on that bank,rotate the crankshaft and watch the rocker arms work on that cylinder,and watch them close completely.Now,install the shop air,and listen for air hissing in the tailpipe,this checks the exhaust valve,and then the intake manifold,this checks the intake valve.Now,you can also listen in the crankcase,and if you hear hissing in the crankcase,then you have bad rings,or a piston with a hole in it.
