Air Conditioning Conundrum - ZR-1 Net Registry Forums

SteelBlueZR1 · 08-22-2012

Has anyone had their air conditioner work perfectly one day, and then the next day go from blowing cold for a half a minute and then only hot air? There are no codes in the auto a/c display, just shows -00.

When the car is stopped now, and I turn on the A/C to Auto the idle speed does not change, nor do I hear the A/C compressor clutch engaging. My 1991 ZR1 has just 8,000 miles and the A/C has worked perfectly before yesterday?!

I have pulled the A/C, Radio and Courtesy fuses, but that did not help... I would expect to get a low freon code if this was the reason for the compressor not engaging?

I am going home to read the A/C Solutions from our site, but wonder if this sounds familiar to anyone, so I can fast track a diagnosis and repair this before Corvettes at Carlisle this weekend?

Does anyone know where I can have the A/C recharged/tested/repaired with R12 refrigerant in Maryland... or does WAZOO have a stockpile of the old stuff
