Hey guys. I need some help. Whenever i start up my truck, and i have all of the doors closed, the door ajar light wont turn off and also the light in my cab wont shut off either. So i checked the fuses and one was blown so i replaced it and it fixed the problem. But now the same thing is happening and i checked and the fuses are fine. What could be wrong?
