Good To Know

Q: Will this switch require a technician to program it to the vehicle? A: These units are generally designed for direct installation, though a simple window limit reset procedure is sometimes necessary to calibrate automatic features.

Q: How can I tell if the switch or the window motor is the problem? A: If the window fails to operate from both the master switch and the individual door switch, the motor or regulator is likely the cause.
