Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Just to let you know you where correct about the connector, when I unplugged it water poured out of the bulkhead. I removed the bulkhead from the floor and throughly clean it with contact cleaner and packed it with dielectric compond. Fuel gauge works fine and the codes have stayed cleared.
Can you answer a question on A/C problems?
Well the van was parked for a year, no use, it was working then.
I can hear the A/C clutch engage but it does not cut out until I turn off the A/C and it does not cool down. I also can hear a boiling / hissing sound behind the dash on the passenger side, I assume this is where the evaporator is located. It stops when I turn off the A/C. I checked the valve that is located on the tube between the rad and engine ( blue cap ) and it has pressure. I don't have a gauge. Is Blue for the low side?
I assume the refrigerant is low due to a leak in the system. I also noticed that the 5V ref controlled a pressure switch for the A/C, so I thought that when I repaired the water problem I'd get lucky and the A/C would work again, but no luck on that.
I realize this might be hard to trouble shoot without taking it to a shop but I thought I'd run it pass you before I do that.
