Why do the interior lights on your 1997 Mercury Mountaineer stay on when all doors closed How do you find sensors that turn off the lights Door ajar lamp does go off?
I'm having the same issue as you are. Reshutting...uh...nearly slamming the doors multiple times eventually fixed it. However the problem is back every day and now the rear interior light won't shut off. All the doors are shut and there is nothing blocking them. I'm still searching for an answer. 1997 Mercury Mountaineer 5.0 L could be that the rear hatch may not be closed completely, i have had the same thing happen on my 1998
