Hello, I am new to this site.

I recently purchased a 1991 Mercedes 420 SEL with 118,000km. The day i brought it home, I opened the sunroof and then it wouldn't close after that. I had to manually close it from the trunk and it hasn't worked since! Attached is a picture of the back of the connector for the sunroof switch. Only the brown and pink wire has power to it only when the car is running. All the other wires are grounded all the time.

I was wondering if anyone knows the problem or if someone has a wiring schematic for it. Anything would be helpful.

Also, the passenger seat doesn't work. The seat jerks on its own ever 10-20 seconds with the car on. But I'd like to fix the sunroof first before I go into that problem.

Thanks in advance
