1997 Mercedes-Benz E420 Problems

Malfunctioning Regulators May Cause Blower Motor Failure

A malfunctioning HVAC blower motor regulator can cause the blower motor to operate below the requested speed or not at all. Updated regulators are available; the blower motor and cover need to be replaced at the same time to upgrade the system.

Mass Air Flow Sensor Failure Causing Poor Fuel Economy and Check Engine Light on

The mass air flow sensor can fail, resulting in poor fuel economy and Check Engine Light illumination.

Evaporator Temperature Sensor Failure

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.
