I'm hoping to get an idea as to what could be leaking, my AC was working fine the night before and now it's blowing hot air... The compressor will not kick on and I found what seems to be a very slow coolant leak from either the condenser or the radiator, I can't find the source of the leak. I'm not very knowledgeable in this subject. I read that if the condenser looses pressure that it would cut the compressor off, is there coolant in the condenser? I assume it would have freon in it. Is it the radiator? and if so,why would that kill the AC? The car stays cool and runs great. Any ideas would be much appreciated.
