Hey Guys,
This question is on a 1995 GMC G2500 Vandura (5.7L). I just bought this Van to trailer my Cobra.
The Air Condition is NOT working. I was told it just needed charging. The compressor is making a very slight rattling sound, but it seems to be kick on when you turn the AC switch off and on.
So,... I recharged the system, but nothing...... (Still Blowing Warm).
I checked the front orphis (Van has front and rear air)... and it was COVERED in little metal particles.... the screen was about 90% blocked. I used a shop vac on the tube hoping to extract any other material that might be in there and installed a new one.
Replaced the O-ring and recharged,... Still blowing WARM.
The pressure gauge was showing about 90psi. (Pretty High)
I let it sit for about 8 hours.
Then Last night (when all was quit around here) and I could hear a HISSING coming from the Compressor.
After further investigation, I found that the Compressor was leaking on the rear around some sensor fitting. When I wiggled the sensor fitting back and forth, the leak got better then worse.
Apparently, there is a snap ring that holds this sensor recepticle in place, obviously with a failed gasket or o-ring.
I have never dug into an AC system. But I thought maybe one of you guys may have an idea about what these symptoms might indicate. ???? Any Suggestions?? (other than buy a FORD Van)
thanks!
