2006 cobalt air conditioner problem

[big gear head]

It just got 100,000 miles on it a few weeks ago.

If in park or neutral does the A/C work without giving it throttle?

 

[big gear head]

I'll have to check that when the car is here again.

 

[YelloEye]

Mine is a stick so I can't stimulate the car being in drive, but I'll see what I get around that 7-800 range.

Any damage to the fan or any debris blocking the condenser? Are the fans on these cars push or pull type?

 

[big gear head]

No, the condenser was just cleaned. I'm going to check the fan myself when the car is here again.

I know I already said this, but have a shop vacuum down the system and charge it with the correct amount. I use to fill them with a can, and then let some out till compressor ran all the time at idle. Worked good for the most part, until there comes along a 100 degree day, and it don't work. Why, because pressure switch says there's a problem and compressor shuts down. They need to be vacuumed to get any air and water out of the system, because like I said they only hold a small amount of Freon (1 or 1.1 pounds).

Ok, I'll check on that when I get a chance. I don't know when I'm going to get to work on the car again. It's 2 1/2 hours away from me and when it's here I dont' get much time to look at it.

Got a chance to look at the car. The compressor runs fine when the car is idling in drive. If I rev the engine to about 1200 RPMs and then let off of the gas the compressor clutch kicks out for a few seconds until the idle speed stabilizes, then it kicks in again. This is why the air gets warm when pulling up to a stop sign. Do they all do this or is it just this one?

Makes sense that it would, I haven't checked mine.
