I am trying to recharge my 02 cavalier with one of those r-134a recharge kits that I bought at auto zone. I am having problems locating the low side fitting. I thought that the fitting with the blue cap was the correct one which is located on the passanger side near the alternator. Unless I need an adapter that isn't the correct one. The only other fitting I found was also on the passenger side all the way forward, with a red cap. that didn't fit either. Can anyone help me locate the correct fitting? Thanks.

manny man: That's it! Make sure you pull the tab back on the refill line you bought. When did you start having trouble with your AC? My 99 cavalier crapped out about 2 years ago and it turned out to be a leaking compressor... just a heads up.
