How do I force A/C compressor on How to jump the A/C compressor on a 1998 LS1 to know it's working?
Freon shows full, like 45 lbs. and relay is good....but no cold air and A/C comp doesn't come on.
Paperclip through the A/C compressor relay? There's 4 prongs, so which ones?
Thanks.

Disconnect the battery for 5-10 mins to reset the computer. If the refrigerant gets low or anything, it throws the AC system into "safe mode" and won't engage the compressor. If that doesn't work, pull AC relay in the power box under the hood, and jump B1 to B4.
Also keep in mind, the AC pump has to be running to accurately measure the refrigerant pressure.

Anyway, recharging a can worked and it's showing 45 lbs. There's a leak somewhere so that sucks. Probably due to not using the A/C enough for 2 years straight and forgetting to turn it on once a month during the winter, etc.
Thanks man, you just saved me a lot of time and at least a few hundred dollars. I was checking the pressure, but the A/C compressor wasn't on and it showed 40 lbs. I didn't want risk overfilling it and thought my compressor was bad. I was going to buy $100 in gauges just to make sure that my old gauge wasn't bad first. If not, then take it to a shop.
