So I have had my 92 300D a year now and it just developed an issue with the fasten seatbelt light, it will not stop flashing. If I open the door the light goes out, however if I shut the door the it starts flashing again. I pulled the fuse for now, I was wondering if there would be somthing else to check other than the door switches? I don't seam to have any other electrical problems. Thank You for your time.

The problem is generally in the driver buckle or the wire going to it.

Have a great day.

Thank you for the infomation. Went to work on it sunday night put the fuse back in to run the wires. The darn thing is working as it should. I don't know if this makes me happy or mad. One thing for sure if it starts again it still drive so I guess I will drive it till it comes back.
