Why Blower Motor Regulator Resistor replacement is so important.

Multi-speed climate control has been around for decades, and is a convenience we all take for granted. Your would not be able to adjust the speed of the air being propelled from your vents without a functioning heater blower resistor. Because it is connected directly to the heater switch, your Mercedes-Benz S420 blower motor resistor modulates the resistance applied to the circuit that handles the load of the blower motor. When the Mercedes-Benz S420 heater switch is set to "Max", there is less resistance in the circuit so more amps go to the blower. And when you switch to low, the heater blower motor resistor raises resistance so that less amperage reaches the blower motor.

You've tried the rest, now try the best.
