After 20 plus years of daily use (at least in Sunny Southern California), the sunroof motor does eventually wear out and fail. We offer them here, at a significant savings versus your local dealer. We also offer here the notoriously failure-prone Transmission Drive Pinion Gear and the ever pesky and troublesome Sunroof Actuating Switch.
The original sunroof crank handle 901-564-085-05 is no longer available. As a substitute, use the emergency crank handle for a power seat and the adapter below:
