Occasional electrical issues. I'm thinking it could be a body ground and looking for some thoughts.

Every now and then my right rear passenger door doesn't cooperate. Locks and window functions just won't work then just like that they do. Another issue is occasionally the dashboard indicator for the front passenger seat belt (or could it be the back seat?} lights up regardless if there is a passenger buckled or not.

Anyone else have a similar issue or knowledge of one?

Door latch perhaps?

 

Check the wiring in the boot between the door and the cab. You might have a damaged broken wire in there.

 

Thanks, I'll look there.
