Why does the Tiguan sunroof fail to close when tilted upwards?

[EvaLynn]

Tiguan sunroof failing to close when tilted upwards is usually caused by foreign objects in the sunroof guide rails or a malfunction of the sunroof motor. If there are obstructions in the sliding rails or insufficient lubrication, excessive resistance may prevent proper closure. First, check the sliding rails: When lubrication is insufficient and resistance is too high, the sunroof's automatic anti-pinch feature will activate, manifesting as failure to close. The main maintenance for sunroofs involves lubricating the sliding rails. Lack of lubrication over time can lead to abnormal noises, poor movement, incomplete sealing, or even jamming and displacement, potentially burning out the motor. Check the electrical system: Inspect whether the electric sunroof's fuse has blown. If the fuse is intact, examine whether the sunroof switch is damaged. Press the switch to check if power is being supplied. If power is present, then verify whether the sunroof's drive motor is functioning by listening for any operational sounds. Additionally, failure to close tightly may be due to obstructions, deformations, rust, or poor lubrication in the sunroof's sliding channels.
