OT (chevy A/C) question
I am trying to figure out why the A/C system on my friends Chevy Tahoe isn't working. Now this Chevy owner is about to buy a Porsche just to let eveyone know.
Anyway the system has freon in it. I checked the pressure at the low side service port with one of those gauges you can buy at Autozone and the pressure is good. It goes up to about 65 when the cluch on the comppressor is off and goes down to about 45 when the comppressor is engaged. So the compressor clutch is engaging and the is freon in the system but no cold air out the vents... so what the hell could it be? expansion valve? Any ideas or touble shooting tips I might try?

I "figgered" it out. The two small O rings on top of the compressor were leaking.
$5.99 for two new ones and three cans of freon later we are back in business. Cold Cold air. Funny thing was she had taken the car to a garge and they had told her the compressor was bad and wanted $950.00 to change it out... can ya believe that?
