I have a 1990 Legacy. The blower and the Max AC will stop working when it gets hot outside. I have located the problem, its the wiring behind the Climate Control Unit on the dash. At first I could just wiggle the wires and the problem was corrected, but now it's getting worse. Yesterday I took apart much of the dash and was able to get to the connections. I can't tell if the problem is the male or female connector that's the problem. Does anyone have a wiring diagram for this (color coded would be nice) or experience with this situation?
