How to Replace the Sunroof Relay on a 1999 Jeep Grand Cherokee
- 1). Shift the Jeep's transmission into park or first gear (manual transmission). Turn off the engine, engage the parking brake, and open the hood.
- 2). Depress the locking tab on the side of the under-hood relay center cover. The center is on the left side of the engine bay, between the battery and the coolant reservoir. Remove the cover from the relay center, and note the diagram on the underside of the cover. This diagram shows the exact location of the sunroof relay within the relay center.
- 3). Remove the faulty sunroof relay, and discard it. Install the new sunroof relay, and replace the relay center cover.
- 4). Test the sunroof to ensure that it operates properly.
