What is the reason why the Mercedes-Benz co-pilot position cannot be adjusted?

The reason why the Mercedes-Benz co-pilot position cannot be adjusted is the front and rear adjustment motor, its circuit failure, or a problem with the seat adjustment switch. Co-pilot seat adjustment method: If it is manual adjustment, the buttons are usually on the lower left and right sides of the seat, or near the door control glass buttons. If it is electric adjustment, the co-pilot electric adjustment allows the seat's front and rear position, height, and backrest angle to be adjusted through motor control. Driver's seat front and rear adjustment: Pushing the control button forward or backward can move the seat to the desired position, and releasing the button will fix the seat in that position. Driver's seat height adjustment: Moving the front or rear part of the control button up or down can adjust the height of the front or rear part of the seat.
I also encountered the issue of the passenger seat not adjusting in my Mercedes. Possible causes include a faulty seat motor, damaged button switch, or blown fuse. The electric adjustment system in Mercedes is quite complex. When the buttons don't respond, first check the fuse box location (usually in the driver's footwell) and try replacing it with a spare fuse. If the motor hums but doesn't move, it might be due to dust or debris stuck in the tracks - cleaning the track grooves and applying lubrication should help. A friend's car once had seat adjustment interference from the seatbelt sensor - unplugging/replugging the seatbelt or restarting the engine sometimes solves this. Don't overlook this issue as a stuck seat could hinder escape during an accident. Get the motor and wiring checked at a repair shop as soon as possible.
