How to Fix the Unclosable Sunroof on Baojun 730?

[McVera]

If you suddenly encounter a situation where the sunroof doesn't close properly during normal use, you can first tilt the rear part of the sunroof upward. After tilting, hold down the switch continuously for about 1 minute. The sunroof will then tilt up a bit more. Try closing the sunroof again, and it should fully close after a while. Here are some relevant details: 1. The sliding mechanism of the sunroof is track-based. Typically, after some time of use (3-6 months), dust and sand particles accumulate on the contact surfaces and gaps of the tracks. If not cleaned periodically, squeaking sounds will naturally occur. Owners can use cotton cloth or gauze to wipe the track surfaces. After cleaning, apply a small amount of grease to the tracks. 2. It's important to note that the sunroof system includes many rubber and plastic components. These materials should not come into contact with oil or sticky substances, as they can cause corrosion. To clean rubber and plastic parts, simply use a clean cotton cloth. After cleaning, you can apply a small amount of talcum powder for protection. The sunroof should be used frequently to prevent squeaking noises.

The sunroof of the Baojun 730 won't close. I've encountered this issue before with similar vehicles. Usually, debris like leaves or dust accumulation gets stuck in the tracks, preventing the sunroof from closing. First, I'd park the car and try manually pushing the sunroof closed slowly to see if it seals properly. If it doesn't budge or moves slightly before getting stuck again, the tracks need cleaning—just remove the debris with a brush or small stick. If there's no manual mode, check if the sunroof switch is functioning correctly; the button might have poor contact or a short circuit from water exposure. After a simple track cleaning, spraying some lubricant can help the sunroof close smoothly. If it still doesn't work, it might be a motor failure. In that case, don't force it—take it to a 4S shop or repair shop for professional inspection to avoid damaging more components. Regular sunroof maintenance is crucial; clean the tracks every six months as a preventive measure.

A sunroof that won’t close is often caused by track blockage or motor failure. Debris in the tracks can easily cause jamming—try cleaning it yourself. If cleaning doesn’t work, check if the fuse is blown or the switch is faulty. Insufficient lubrication in the tracks increases friction—try applying some WD-40. If that doesn’t help, listen to the motor: if it hums but doesn’t move, the motor is likely broken and needs replacement. Manually pushing it closed is a temporary fix, but not a long-term solution. Loose wiring in the controller could also be the issue—check the plug connections. To prolong the sunroof’s lifespan, avoid parking under trees to reduce debris buildup. If you notice any sunroof issues, address them promptly—ignoring them could lead to leaks and bigger problems.

A sunroof that won't close is dangerous, especially when rainwater leaks in and floods the car. If you notice it's not sealing properly, don't drive—turn off the engine immediately and check the tracks. Remove any debris yourself or use an air gun to blow it out. If manual closing doesn't work, it might indicate mechanical damage, such as deformed or jammed tracks, requiring professional repair. Safety first—avoid opening the sunroof at high speeds to prevent objects from flying out and causing harm. Park in the shade regularly and wipe down the sunroof gaps after rain to prevent rust.

If the sunroof won't close, try these simple and cost-effective solutions first: After parking, manually push the sunroof to try closing it tightly. If that doesn't work, check if there are leaves or dirt blocking the tracks, clean them out, and lubricate. Look at the fuse box to see if the sunroof fuse is blown—if it is, replace it for a low-cost fix. Also, check if the switch button is unresponsive, which might indicate poor contact. Regular cleaning of the tracks can save money by preventing issues. If you can't fix it yourself, opt for an affordable inspection at a local repair shop.
