What are the reasons for the failure of the four sunroofs in the Teana?
2 Answers
The reasons for the failure of the four sunroofs in the Teana are as follows: 1. The window lift motor is damaged or there is poor contact in the electrical wiring harness: If there is a burnt smell or abnormal noise inside the door panel when holding down the window button for a long time, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly contact a 4S shop or auto repair shop to replace the window lift motor. 2. Motor overheating protection: To protect the power supply circuit, most window lift motors have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window lift to fail. 3. Excessive resistance in the glass guide channel: During use, dust can accumulate in the door glass guide channel, increasing resistance, which over time may make it difficult for the glass to rise smoothly.
I've been driving a Teana for over a decade, and there are quite a few reasons for sunroof malfunctions. The most common is a blown fuse—just locate the corresponding position in the car's fuse box, and replacing that tiny fuse might solve the problem. Motor failure is also frequent, especially after frequent use or prolonged operation, as the motor can overheat and stop working. Wiring issues like short circuits or disconnections, often caused by rainwater or aging, can trigger electrical faults. Poor contact in the switch button, where pressing it yields no response or it gets stuck, is another culprit. Additionally, clogged guide channels, with dust or leaves blocking the moving tracks, can cause issues. Prevention is simple: regularly clean the channels, lubricate the sliding rails, and pay attention to waterproofing during rainy seasons. If the sunroof malfunctions, address it immediately to prevent water leakage into the car or compromised driving safety. It's best to have it professionally inspected at a shop rather than tampering with the wiring yourself, which could lead to more problems. These small details can save you a lot of hassle.
