Question about 1995 Chevrolet K1500
The A/C on my 1999 GMC Sierra 1500 blows hot air when I'm idling. When it's moving, it blows cool air, but not cold. I'd like to try recharging it, but I cannot find the low pressure port on it. Can you help me find it? I've read some people saying that it's near the grille, but I can't find it. I think it's low on R134, but the compressor doesn't shut off and on like it has on my other car when it was low. Does it need to be recharged, or is there something else going on with it?
The low pressure port is the charging port, this port is either in the low pressure line or the accumulator that the low pressure lines to to (can shaped object), the low pressure line is the larger of the two lines from the compressor.
