Hey guys i'm new here on the site and i'm looking for alittle info. I have a 02 f150 crew cab and last night the door ajar light stayed on in my truck which kept my dome lights on. I check all the doors and none were open. now this morning its working normal. Does anyone no what could be up with this? A switch or something? Any info would be great!!

 

I have the same problem with mine i have a 97 f150 extended cab door ajar stays on with the dome light and the 3rd brake light white lights. It only does it when its hot outside tho never when its cool out its weird and i have no clue what it is lol. But you get use to it lol.

 

Idk what the correct fix is but I took the driverside door sensor out of the door an it fixed it and the dome light still comes on when I open my door but shuts off right away when I shut it

 

I was told on a different site that the door mechanisms are known to stick and to spray them with wd40 on they will losen up and work. I tried it last night and it fixed my problem. It was in passenger door that was stuck. I how this will work for you guys.

 

Awesome ill give it a shot tonight! thank you

 

x2 on the wd40 or penetrating oil.

did it about 6 months ago and no problem since

 

Did you guys take the door panel off or just spray the rod that slides in and out the slot in the body?
