HVAC Controls
I own a 1985 500SL and had the air conditioning replaced, and it was working great. Then suddenly it stopped working. When I first got the car, The HVAC control panel was replaced because the original one wasn't working, and the Mercedes mechanic told me they don't last. The fan on/off buttons don't work now. How do I check to see if the control module is the problem?
