Good To Know

Q: What is the main cause of resistor failure? A: Overheating, often caused by a clogged cabin air filter or a worn blower motor drawing too much current, is the primary cause.

Q: Where is this regulator located? A: It is typically mounted directly in the blower motor housing under the dashboard or behind the glove box.

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