How to Reset the Buick Excelle Sunroof?
2 Answers
To reset the Buick Excelle sunroof, first press and hold the close button for 10 seconds. The sunroof will automatically open and stop at the raised position, then release the button for 1 second. Press and hold the close button again; after 5 seconds, the sunroof will automatically lower, slide open, slide closed, and stop. Once the sunroof stops moving, release the button. Here are some additional details: 1. The Buick Excelle comes with a power sunroof in all versions except the base model. The sunroof control switch is located near the front dome light, and the ignition must be turned on to operate the sunroof. If the sunroof won’t close, first check if there is any debris like dust or leaves stuck in the sunroof’s sealing rubber or tracks. Clean the sunroof seal and roof sealing area with a clean cloth, mild soap, and water. 2. If the Buick Excelle sunroof isn’t closing due to debris in the tracks, try troubleshooting. If the sunroof can open but not close, the sunroof motor is likely functioning properly. If the sunroof won’t open or close at all, the issue could be a blown fuse or the motor entering protection mode from frequent operation. Replace the fuse or wait for the motor to cool down.
I also encountered the issue of needing to reset the Buick Excelle's sunroof last time. It's usually caused by a disconnected battery or the sunroof getting stuck. The reset operation is actually quite simple: first, manually close the sunroof all the way down and make sure it stops firmly; then, continuously press and hold the sunroof switch's open button for about 30 seconds until you hear a click or see the sunroof move slightly and stop. This process allows the sunroof to relearn its position settings, preventing further misalignment. Remember to have the car key in the ACC position or the engine running during the operation to ensure stable voltage. Additionally, sunroofs tend to accumulate dust during regular use, so it's recommended to clean the sliding rails periodically to prevent such issues. If the sunroof still doesn't work after resetting, it might be due to faulty wiring or a broken switch, and you should visit a 4S store for inspection.
