Recently the "door ajar" light stays on after getting in my truck as if one of the doors is opened. I always check and neither door is opened but securely closed. This prevents the automatic door locks from activiating when I put the truck in gear. However, after a few minutes or so, the light goes out and the doors lock.

Does anyone know what's causing this and how to fix it?

Thanks in advance.

 

Wd40 the latch assembly on the door and open and close it a few times then repeat
