Chevy Monte Carlo A/C Blows Warm Q. The problem I am having is I got my A/C Charged last summer. It blew very cold. The place were I took it said there was no leaks, it was fine and just needed charged. It blew cold all last summer. I really don't use it to often, only when I go on the highway. This summer I used it a few times and it worked fine. This past weekend I tried using it and it did not blow cold. Is there anything I could check that could be the problem? 1996 Chevy Monte Carlo LS 3.1 liter V-6 89,000 miles Automatic transmission Fuel Injection ABS brakes P/S, A/C Thanks...

A. There are two things that need to be checked. First is for pressure in the system. If too low, below 40 psi, the compressor won't come on as a precaution so the compressor won't starve for oil. If there is pressure in the system, then a check of the compressor controls needs to be looked at.

This would include the control head, PCM, and wires from the control head and all the switches in the system. A/C systems don't "just need a re-charge"! If they need a charge there is a leak! Have someone add ultra violet dye to your system to see if a leak can be found.
