What Causes the Sunroof Failure in Baojun 560?

Baojun 560 sunroof failure may be caused by circuit faults or blown fuses. Circuit Faults: Sunroof circuit malfunction or damage to the sunroof drive motor. Severe lack of lubrication in the sunroof tracks can cause the sunroof seal to adhere to the car body. Obstruction in Sunroof Track: It is recommended to first check if the sunroof fuse is blown. If the fuse is intact, inspect whether the sunroof switch is functioning properly. Press the switch to check if there is power. If there is, then examine whether the sunroof drive motor is operational. Listen for any sounds of the motor working. Additionally, if the sunroof doesn't close properly, it might be due to obstructions, deformation, rust, or poor lubrication in the sunroof track. Meaning of Sunroof: The two sides of the sunroof are sliding tracks that ensure the sunroof moves back and forth. At the front corners of these tracks are the sunroof drainage holes. Common Sunroof Issues: Blocked or broken drainage pipes can lead to water leaking from the sunroof seam into the interior. If the pipes are broken, it can also cause water seepage in the car's A-pillar or C-pillar. Another common issue is the aging of the sunroof's sealing strip, which can result in water leakage.

My Baojun 560 also experienced the sunroof malfunction. Later at the repair shop, they found leaves and mud stuck in the guide rails, and the motor was caked with dirt. The mechanic said domestic sunroofs with anti-pinch functions are particularly prone to jamming when dust accumulates in the tracks, especially during rainy summers when dust hardens. He disassembled it to clean the tracks and applied lubricant to the rubber seals, which fixed the issue. As a reminder: if you hear the motor humming but the sunroof doesn't move, don't force the switch—it could blow the motor fuse. Regularly clean the guide rail gaps, especially after rainy seasons.

Last time my friend's 560 sunroof malfunctioned, I helped diagnose it and found it was a blown fuse. The location is in the fuse box at the lower left of the driver's seat, marked as ROOF - that 15-amp blue mini fuse. Spending 5 yuan to replace it solved the problem. However, be aware that frequent fuse blowouts might indicate a short circuit in the wiring. I've also encountered cases where the control button had poor contact - the rubber pad aged causing button failure, which was fixed by spraying some precision instrument cleaner. Additionally, prolonged non-use of the sunroof can lead to mechanical jamming, so it's recommended to open and close it at least once a month.

This issue commonly stems from several causes: foreign objects jamming the track triggering the anti-pinch function; motor overload burnout; or clogged drainage tubes causing water leakage and short circuits. Last time we handled a flood-damaged vehicle where the drainage holes were completely blocked by leaves, allowing rainwater to seep into wire harness connectors causing oxidation. Inspection requires removing the A-pillar trim panel to examine wire harness connectors. Here's a lesser-known tip: power interruption activates the sunroof protection mechanism, requiring long-press switch operation to relearn the travel path. If performing DIY repairs, remember to disconnect the battery negative terminal first.

From my experience, the issues mainly fall into three categories: track problems account for 70%, caused by aging or deformed seals squeezing the space; 20% are due to motor issues, such as worn carbon brushes or missing gear teeth; the remaining 10% are control circuit faults. There's a clever detection method: use a wrench to turn the hex shaft of the sunroof motor. If it can be manually opened and closed, the track is fine, and the fault lies in the circuit. If it can't be turned manually, it's likely due to debris in the track or a rusted motor. The design flaw in the 560 is the poor waterproofing of the motor, making it prone to water ingress when directly hit by a car wash pressure washer.
