What Causes the Rear Tilt of the Yeti's Sunroof to Fail to Close?
2 Answers
The failure of the rear tilt of the Tiguan's sunroof to close is typically caused by obstructions in the sunroof guide rails or a malfunction in the sunroof motor. If there are obstructions in the sliding rails or insufficient lubrication, excessive resistance can prevent the sunroof from closing. First, inspect the sliding rails: When there is insufficient lubrication leading to excessive resistance, the sunroof's automatic anti-pinch feature will activate, resulting in the sunroof failing to close. The primary maintenance for sunroofs involves lubricating the sliding rails. Lack of lubrication over time can lead to unusual noises, poor movement, incomplete closure, or even jamming and misalignment, which can burn out the motor. Check the electrical circuit: Verify whether the fuse for the electric sunroof has blown. If the fuse is intact, check if the electric sunroof switch is damaged. Press the switch to see if power is being supplied. If power is present, then check if the electric sunroof's drive motor is functioning. Listen carefully for any sounds indicating motor operation. Additionally, the sunroof may not close properly if the sliding grooves are obstructed, deformed, rusted, or poorly lubricated.
I've seen quite a few cases of Yeti sunroofs failing to close when tilted at repair shops, usually because leaves or small stones get stuck in the roof rails, jamming the mechanical parts. Aging slide rails lacking lubricant increase resistance, making it hard for the motor to pull the tilted section; sometimes the electronic control module malfunctions and requires a reset initialization. It's advisable to first park and inspect the rails, clear any debris, then apply some specialized lubricant. Parking away from trees to minimize debris accumulation can prevent such issues. The key is timely action to avoid water ingress during rain or accidents at high speeds.
