1992 Mercedes-Benz 600SEL ProblemsBad Switch/Blower Motor Resistor Assembly May Cause Inoperative Heater Blower Motor
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.
A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.
A refrigerant leak may develop from one or more of the following AC components: AC compressor, hose manifold for the compressor, or the evaporator core. The loss of refrigerant can cause poor AC performance. Our technicians tell us that proper leak diagnoses should be performed in order to determine the cause of any refrigerant loss.
1992 Mercedes-Benz 600SEL Questionsheating and air (1 answer)
after leaving my car in the garage for one year, now the heating and air conditioning display will not come on(dead) and there is no way to control ac/heat althaugh if I drive it I will get hot air from vents but not regulated by the fan that I can not control due to no active display .
Just want to replace the fuel filter and don't know where it is.
1-2 minutes after starting the AC, the air from the center air vent gradually stops blowing and redirects to the windshield vent. This happens when I first start the engine. What can cause the fopper to close? is is vacuum hose leak or is air solenoid probelm???
