There is a preset sequence for activation of pump. I believe it to be 45 seconds after ignition is turned off and again around 1 hour. These are set to purge the system and then recharge it. Why it does this I'm not sure but this is what was explained to me by dealer. Hope this helps.

How can you bypass the AC compressor if it is making a grinding noise on a 1994 GMC Sierra?

If you want to remove the Ac compressor completly, you can pick up a bypass pully and bracket at Murray's or Pepboys for around 25 bucks. It just bolts implace of the compressor and reuses the stock belt. You might have a worn bearing on the compressor shaft which could cause the grinding noise. Make sure that it's the AC compressor that is grinding, they can be quite costly. Hope this helps.

Why does the AC in a car make random noise at random times when it is on?

To prevent icing up, the AC compressor only turns on when the "low side" pressure is above a certain set-point. Once enough refrigerant has been pumped out of the low side, the compressor shuts off momentarily. When it comes back on it may make some "random noise".

The compressor, along with several other parts make up the ac system. The most common part to go bad and need replacing is the compressor.

What causes the AC compressor on a 1996 Jimmy to whine when accelerated and the compressor clutch is engaged when it works fine otherwise?

Make sure its the ac compressor making noise. The idler pulley and belt tensioner can make alot of noise, also. If you haven't replaced those, I'd start with that as it's a fairly inexpensive fix. If the noise doesn't go away, no harm done because those components should be changed every so often anyway. (belt tensioners lose spring tension over time). If you're sure it's the ac comp., the compressor bearings are probably going bad and you'll need a new one. I have a '99 Jimmy and the comp. started leaking oil from the front seal a few months ago. Still blows could air, but recently started making noise. I'll be replacing it real soon.
