Solutions for when a car sunroof fails to open include: 1. Replace the sunroof fuse; 2. Repair or replace the sunroof drive motor; 3. Apply lubricant to the sunroof tracks; 4. Remove any debris from the sunroof guide channels. The reasons a car sunroof may not open are: 1. Faulty sunroof wiring; 2. Damage to the sunroof drive motor; 3. Lack of lubrication in the sunroof tracks causing the seal to stick to the car body; 4. Debris in the sunroof guide channels. Maintenance methods for a car sunroof include: 1. Regularly clean the channels and gaps; 2. After snow or washing the car, open the sunroof and wipe the edges dry; 3. Avoid fully opening the sunroof on bumpy roads.
I was really worried when my sunroof got stuck last time, and later found out it was due to small stones stuck in the tracks. Don’t force it open—first try a power reset: turn the car key to the accessory position (without starting the engine), then hold down the sunroof open button for over 30 seconds. Most models will reset the program this way. If you hear the motor humming but the sunroof doesn’t move, it’s likely a track blockage. Use a vacuum to clean the guide rail gaps, then apply track lubricant with a cotton swab. For cars with sensitive anti-pinch functions, even a small branch can trigger a shutdown, so carefully check all four corners of the sunroof for debris. During the rainy season, pay extra attention to the drainage holes—keep a thin wire in the trunk to unclog them, as water buildup leaking into the motor can cause bigger issues.
