Mercedes-Benz SL320 Problems

Bad 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.

Erratic Engine Operation and Poor Fuel Economy Due to Faulty Mass Air Flow Sensor

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.

Poor AC Performance Due to Refrigerant Loss

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.
