I have yet another question about our 1995 Chrysler Concorde. Last time I used the car, about a week ago, the heat/AC was fine. I got in the car yesterday and the heater was stuck on “on.” I didn’t turn the heat or or leave it on last time I used the car. If anything, I had on the AC last time because it was very warm in the Boston area last week.
The controls will not work at all – not for the AC, heat, vent, etc. Pushing the buttons and turning the knobs has no effect on the speed of the blower/fan or the temperature. It’s stuck on full fan and full hot. The panel that displays the temperature does not light up. All other instruments, radio, etc. are fine.
Ideas? Is this something we can fix myself ourselves, or do we need to take it to the garage? Thanks!
