Working on climate control vacuum
My climate control has risen to the top of the priority list. I can get heat but not cold air want to start by having air blow out the correct vents before messing with the compressor.
There is still some R12 in the system but I haven't found my gauges to test the pressure. The compressor comes on but is noisy. Switchover valves 13 & 17 in the attached diagram don't hold vacuum. Air always comes out the defroster vents and the center vents but not the side vents. Center vents shut off when switched to defrost. 13 connects to pod 38 (defroster) and pod 40. 17 connects to pod 42 and pod 43. I'd like to patch as little as possible until I get time to pull the dash and fix whatever is under there. Which pods need to be changed (38, 40, 42 &/or 43)? Any other comments?
