Good To Know

Q: What is the main symptom of a failed blower motor resistor? A: The most common symptom is the cabin fan only running on its highest speed setting or not running at all.

Q: Should the blower motor be inspected when replacing this resistor? A: Yes, a worn blower motor that draws too much current is often the primary cause of resistor failure.

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