What is the fault when the sunroof does not respond when pressed?

First, check whether the fuse of the electric sunroof is blown. If the fuse is intact, check whether the switch of the electric sunroof is functioning properly. Press the switch to see if there is power. If there is, then check whether the drive motor of the electric sunroof is working by listening for any sound of the motor operating. Additionally, the sunroof not closing properly may be due to obstructions, deformations, rust, or poor lubrication in the sunroof's sliding tracks. Sunroof maintenance methods are as follows: 1. Do not use the sunroof too frequently: Although the sunroof is part of the car window, its mechanical structure is different from that of the door windows and is much more delicate, so it should not be used too often. 2. Do not open the sunroof immediately when the car is cold in winter: Winters in the north can be extremely cold, and after the car has been parked overnight, the edges of the sunroof may be frozen by dew, making it temporarily impossible to open. At this time, the owner must not open the sunroof immediately, as snow in the sunroof's grooves can increase the resistance to opening, and blindly operating the sunroof may cause the sunroof switch motor to burn out.
The sunroof isn't responding when pressed, an issue I often encounter. Usually, it's a fuse problem—check the corresponding fuse in the engine compartment's fuse box to see if it's blown, then try replacing it. It could also be an unresponsive switch button, with dust stuck or worn contacts; clean it or press it a few times to see if there's any response. Blocked tracks or insufficient lubrication can also cause sticking, especially after rain when dust accumulates and hinders operation. Once, I had to replace the motor because it overheated and burned out, which was quite a hassle. I recommend not forcing it to prevent worsening the issue. Regular cleaning and lubrication of the tracks can help prevent problems. If none of these work, it might be a control unit failure or a short circuit, requiring a diagnostic tool to check. Get it repaired promptly to avoid affecting ventilation and mood during trips, otherwise, long drives can feel stuffy and uncomfortable.
