door ajar,dome light.and cab lights are staying on when I start or turn of my truck, wont go out.

 

We cant help you if you dont give us any information about what truck you have and this is the engine forum you should post this question over on the correct year (1997-2003, 2004-2008 etc) truck forum. Before you do that fill in the info in the user control panel so your truck info automatically shows up like mine does in every post.

 

Spray some WD40 in the latch mechanism. That usually takes care of the problem.
