Air Conditioning problem
1996 Chevy Tahoe V8 Four Wheel Drive Automatic 200K miles
----------------------------------------------------------------
I'm trying to recharge my air conditioner, but can't remember which is the low pressure valve. How can I tell which one it is? Also, can you quickly run me through the whole procedure, it's been 2 years since I charged it last. I have the hose, pressure valve, and refrigerant.

The hose, pressure valve will only install on the low side. Add refrigerant with the air conditioning on and set to high -- engine running. Add enough to get the pressure gauge in the green area.

ASE and GM suggest charging refrigerant on the low side.
