The A/C and Heater control head was not cooling, a used one was purchased and the A/C is now working but the HEATER is not. The dashBOARD center Vents(The Three FrontONES), not the Two left and Right vents are IS NOT WORKING. The A/C shop in my area says that I need to reprogram the system because His Scanner shows that all the motors are not working.What do you think?
The center Air vent is not working properly. The heater is not working. on 2003 Mercedes-Benz ML320
