Hello,
My a/c was working fine before but, I've let my 83 300SD sit since February and it needed a recharge. I tried to put some 134a in it and it seems like there is a leak in the compressor - you will see all kinds of gas come out of the compressor through the belt that turns it when you try to recharge it and you can hear it hissing out. When I first turned my A/C on after 5 months it actually caused the car to stall. Is the compressor dead does it need O-rings?
thanks,
Tom Martin who is prepare to be called an idiot.
