Replacement Sunroof Module Motor Harness Connection Changes - kw plug terminal

The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Replacement sunroof module motor harness connection does not fit in-vehicle connector.

A second design motor/module was released for 1996 - 2002 sedans and 1997-2002 coupe vehicles. The second design motor has a pigtail wire harness instead of a fixed type connection.

When installing a second design sunroof module into a vehicle that was originally built with a first design sunroof module, a Sunroof Switch Wiring Harness Assembly, P/N 21054119, must be used to connect between the headliner harness and motor.
