The reasons why the car sunroof cannot be opened are: sunroof circuit failure; damage to the sunroof drive motor; the sunroof seal is stuck to the car body; foreign objects are stuck in the sunroof slot. Below are the maintenance methods and components of the sunroof: Sunroof maintenance methods: Clean foreign objects regularly to prevent them from affecting the opening of the sunroof. Otherwise, if the sunroof track is scratched, it may be difficult to open at best, or completely unable to open at worst, requiring replacement of a new track. Apply oil or lubricant to the track in a timely manner. First, clean the sealing rubber and track thoroughly with water. Since oil tends to accumulate sand and debris, wipe them again with a damp cloth to remove all grease and keep the track clean. Then reapply oil to ensure smooth sliding of the track. Components of the sunroof: Sliding mechanism; drive mechanism; switch; control system.
Last time I encountered a situation where the sunroof wouldn't open, I found that too much dust and debris had accumulated in the roof tracks, causing the sunroof to get stuck. This mainly happened because I often parked under trees, allowing leaves and small insects to fall in and block it. After gently cleaning with a soft brush, it worked normally again. Remember, never force it open by hand as this might damage the motor or pull on the cables. I recommend performing simple maintenance annually, such as spraying dedicated cleaner on the tracks to prevent issues. Try to park in underground garages when possible to minimize external contamination.
