Hi all, AC crapped itself on my Z. My climate control are the early model auto ones. Blower works fine and responds to hi/lo settings accordingly. Heater also works and warms the car up fine. But no cold air! Suspected it could just need a regas as I've recently only bought the gas and the previous owner just mentioned he had it regas but no proof. Took it to a AC shop near my work and they took a look, said it had no more gas. They did a test for leak and could not find any leak so went ahead and regassed. Eventually they diagnosed that the ac compressor wasn't running and they suspect the air con amp is faulty. They bypassed it with a switch and ac runs. It is a 'band-aid' solution in my opinion and I'd like to fix the issue properly. Are the AC guys I went to correct in saying the amp is definitely the cause? Because they have quoted me to take dash out and replace the amp (big labour $$$)!!! What I don't understand is that (if previous owner did get ac regassed) how come it ran out of gas so quickly? Surely there must have been a leak somewhere but AC guys I went to can't find it? Perhaps there is another solution to this problem - what are other possible causes for no cold air?
