Mercedes-Benz SL500 Bad Switch/Blower Motor Resistor Assembly May Cause Inoperative Heater Blower Motor

(10 reports)

Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.

OK when purchased in March, 2013. One or two instances of blower malfunction (slow speed). Seems to be working at present (Aug 2013). -
