Mercedes GLC Electric Seat Issue

I have a similar Mercedes and had a comparable power seat issue. Have you checked the seat harness and connections? A loose or corroded connection can cause failure. Are any other electrical components malfunctioning, or just the passenger seat?

Thanks for the reply. When you had this issue, were there any strange noises from the seat motor before it failed completely? Did you try any troubleshooting before getting professional help?

I didn't hear any noises before my seat stopped working. I checked the fuses, but that's all. Since the error memory has a fault code and you've checked the battery, a qualified Mercedes technician is probably best. They can find the cause, like a bad seat motor. I paid around 300€ at the workshop, and they replaced my heavily discharged battery.

I appreciate you sharing your experience. It confirms I need a professional diagnosis. I'll make an appointment with a technician to investigate. The estimated repair is about 290€. Thanks again for the help.
