Good To Know

Q: Why do blower motor resistors fail? A: They often overheat due to a worn blower motor that draws too much current, or from restricted cabin air filters.

Q: Where is this resistor typically located? A: It is usually found behind the glove compartment or under the dashboard, mounted directly in the blower motor ducting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
