Good To Know

Q: Do I need to program this switch after installation? A: No programming is required, but you may need to perform a simple manual reset procedure to activate the auto feature on some doors by holding the switch up for several seconds. This syncs the motor with the new switch.

Q: Why do driver side window switches fail more often? A: The driver side switch controls all cabin windows and gets used far more frequently, exposing it to more moisture, dust, and electrical wear.

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