Can the keyless entry cause interior lights not to working properly? The interior lights on my car are not working, and I replaced the door jam pin. I don't think that this is the problem, because when I open either door, the "Door Ajar" light comes on. The headlight switch could be the problem, maybe not, but when I need to use the interior lights, I can do so using the headlight switch. So, could it be a defective keyless entry. Problem is with my 89 LX.
