Please help Expert wanted! 2014 countryman door ajar issue
Hi everyone I have a 2014 countryman, the damn lights won't turn out. I looked at it and realized the computer says the door is open when driving but checked when parked the door and door latches and I cant find the issue. I held down the interior light button for 15 seconds to reset the lights but it only turns them out and the computer still says door ajar passenger rear when driving. Is it the door sensor? Can this be fixed by a fuse? I checked some fuses but didn't find any issues there. If it is a door sensor how much would that cost to fix? and would I need to take it to mini which would cost an arm and a leg. Any advise? I read online to try wd40 but I am afraid of ruining wire etc please help!!!
