Help: Interior Light/Open Door Issue
So, I went to start up my 1987 300 SDL today and although the glow plug seemed to light up, the car failed to start.
I thought maybe I left the lights on and the battery was dead, but that wasn't the case.
Anyways, after some investigation, I realized that the passenger door light on the driver's side was on, even when the car was off. It's the light below the ashtray/lighter. I checked all my lighting switches and that wasn't the issue.
I took the car in for an oil change two days before, and noticed when I got in the car and put the key in the ignition, I was getting the warning alarm that sounds when the lights are on or when a door is ajar.
I now think they might have messed something up while they were vacuuming out the back seats, and now the car thinks the side door is open, even though it's not, so the light never went out, and it drained the battery.
My question is how can I fix this issue? Can someone tell me where the door ajar sensor is on the passenger doors? Is this something I can fix myself?
It's my main car, so I need it fixed badly so I don't get stranded with a dead battery.
Thanks so much for any help/advice.
