AC Help
AC Help I just replaced my whole system last year with an AC delco Compresser $$$ 
and now its not working again.. The weird thing about it is that the other day my battery went dead and after I jumped the car the AC started working again, at least until I turned it off.
Now I cant get it to work again. any help is appreciated.

Have you checked the compressor relay? Swap it with the fog light relay... is the compressor kicking on at all? You may have a leak in one of the lines causing 134a loss. If the level is low the compressor will not work. Get a pressure check done on it...
first thing i would do is check the pressures and/or recharge the system using a robinair machine or similar (not the little cans u can buy at the parts store) then when u know the charge is good, go from there as far as troubleshooting it

Pressure 1st then everything else down the line.

I do agree with a pressure check. Not necessarily a vacuum check but a pressure check. Go to a shop and get them to vacuum it, and do a dye pressure check. Sometimes a hose will crack lengthwise, and when you pull vacuum it won't leak as it will close in on itself. But when pressure is applied when refilling, it will open up and leak. But first, check the relay. There are two fuse panels under the hood. The fog relay and a/c relay are clearly labeled. Switch the two and see if your fogs work. If so, the relay is good. Then go for the pressure check...
