Hello All,
I have a problem with the climate control system in my 1993 320E. The problem I am having is that most of the time I can only get warm air out of the outlets on the left hand side of the car. If I move both temp controllers to a warm setting I get warm air out of the outlets on the left hand side and ambient from the right. If I select the left temp selector to a warmer setting I get warm left and ambient right. If I only select the right hand temp selector to a warmer setting and leave the left selector then I get warm air from the left and ambient from the right. The only way I have managed to get warm air out of the right hand side is when the left temp selector is on full warm and the right is on an intermediate setting. I have used the search and have not found any similar problems posted. Any suggestions for how to try to troubleshoot and fix?
Attached is picture of my heater panel.
Thanks in advance,
Chris
