What Causes the Sunroof to Not Close and Stay Tilted Up at the Rear?
3 Answers
The reasons why the sunroof cannot close and remains tilted up at the rear may include debris in the sliding tracks, switch malfunction, system short circuit, etc. Below are the specific causes: Debris in the sliding tracks: Some car models have an automatic anti-pinch feature for the sunroof. If there is debris obstructing the tracks or insufficient lubrication, clean the tracks and apply lubricant. Switch malfunction: Check if the sunroof switch is faulty. Try pressing the sunroof buttons to see if there is any slight vibration. System short circuit: A short circuit in the sunroof's electrical control system may cause the fuse to blow. Replace the fuse in this case. Motor burnout: If the sunroof was not properly closed before, it could lead to overheating and burning out of the motor. In this situation, you should visit a 4S shop or an authorized repair shop for inspection and repair.
When the sunroof won't close and the rear part remains tilted, I suspect it's mostly due to issues with the track system. Dust, small stones, or leaves might have accumulated inside the tracks, obstructing the smooth sliding of the sunroof, causing it to get stuck midway with only the rear part tilted. Another possible reason could be insufficient power or aging of the sunroof's drive motor, leading to incomplete closure. This is more noticeable in winter when ice forms. If the electrical contacts are loose, signal interruption could also cause this issue. It's recommended to first try cleaning the tracks—use a soft brush to remove debris or spray some specialized lubricant and wipe it down. Remember to wear gloves before handling, and avoid forcing it to prevent damaging the wiring harness. For safety reasons, if the problem persists, it's best to seek professional repair to avoid damaging the motor. This situation is quite annoying while driving, and rainwater seeping in can damage the interior.
My old car's sunroof did the same thing last year, getting stuck halfway open was really annoying. After checking around, I found bird droppings and sand had accumulated in the sunroof tracks, causing a blockage over time. The experience of cleaning the tracks myself taught me a lesson: wiping the sunroof gaps while washing the car is basic maintenance, otherwise dirt buildup can jam everything. Another possibility is if the motor gears are worn or lack lubrication, the reduced power might only move the rear half. As for solutions, I once fixed it by disconnecting the power for 5 minutes to reset the system. Remember not to leave items like sunglasses or phones on top, as they can easily become sources of trouble. Since then, I've made it a habit to check monthly to keep it clear. Sunroof issues need timely attention to avoid leaks or hazards at high speeds.
