28 Amp blower resistor which controls the heater and A/C blower motor speed. Often, if this unit is burned out, the blower will only operate at the highest speed and none of the lower speeds.
For all vehicles with Tempmatik Climate Control: This is used for both the main heater and A/C blower motor, as well as those models equipped with roof-mounted rear A/C. Check your version before ordering.
This is an original Behr product and is the exact same unit sold at a Dodge, Freightliner or Mercedes dealer.
