Mercedes-Benz E320 4MATIC Erratic HVAC Blower Motor Operation
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.
