Just took my car into an indy shop to get a 134a charge and to check for leaks. The mechanic filled it up, but a/c still blows warm air. The compressor and clutch, etc. all seemed to be engaging, but when he checked his guages, the low side readings were too high, and the high side was too low or barely showing any pressure. He did clean out the system before recharging the a/c.

Is my A/C compressor bad, and I have no choice but to have it replaced, or could it be something else?

FYI, it's a 99 clk320, purchased April 03 from some private dealership in VA. (I live in NY) Only work done recently was 60k service. They did have to replace a cracked pipe leading to my intake manifold, but nothing else. My check engine light also just came on (bad MAF), but the mechanic doesn't think its related to my A/C woes.

Wifey is NOT happy....
