ok so had to do a little Jerry rigging on the way to Florida. My A/C stopped working all together. The clutch wasn't engaging at all. so i removed the system pressure switch and bridged the terminal with a paper clip and the clutch kicked on and a/c started to blow cold air. That was the best I could do at the time seeing as how I was in Florida and my children were in the back seat. The a/c worked fine except for the rear a/c all the way until we got home at which point it stopped blowing cold. I checked the system and charged it to proper psi but clutch still does not engage. I bridged the terminal on the pressure switch again but still has a loud squeal and no cold a/c. any help is appreciated
