Climate Control on 01 Regal LS
I have a 01 Regal LS with dual climate control, nothing fancy, just the push buttons, rotary switches and sliders. a couple of weeks ago everything completely quit. it will work once in a while, but usually not. the electrical side acts like it has no power. I can hear the vacuum operated vents move when i switch from defrost to vents, but no fan, rear defroster or A/C, like the main power to them is gone, fuses are good, as I said before, it will work some times, like dirty contacts in a relay. is there a relay for the climate control system? and if so where. when it was working intermittently I switched the fan on and off and heard some clicking under the dash, when it'* not working I hear nothing when i switch it on and off. I have used the Haynes service manual to try and track it down, but the manual covers so many different other cars and years it does not specify the relay or locations. I have plenty of mechanical experience, but it is mainly in the marine industry and not electrical automotive. Please help, not defrosting in the morning is troublesome to say the least.
