Why is Message 'door ajar' lit when doors are all closed

Thanks! I will give this a try!

You can just spray the heck out of ALL latches then close/open the door several times, flush and blow latch out again until it starts working... Now it may be a failed swith that will have to be replaced.. Have had pretty good luck with cleaning though!

Thank you so much pushrod! Been trying to figure this out for a year! I did the WD-40 and air gun twice and work like a charm! I have my dome lights back!

Glad you got it fixed!

Pushrod. Impressed. I have issue 2014 Lincoln MKX "Door is Ajar" and "Transmission Not in Park" idiot lights with alert noise. Any ideas?
