Dash lights half lit and stay on after turning off car. By dash lights i mean the odometer reading and PRND21 lights. also the Tach needle is at 1000 rpms and didnt fall to 0 after shutting off car. Light that says door ajar is lit and all doors are shut tight. Temp out side is down to 15 degrees I live in Central Pennsylvania but i dont think that the weather is the reason. Any body help me here , thankyou yancy C.

Hey Jared..my name is Keith..and what you have is a bad door sensor..and you will have to see and figure out which one is bad..i had a bad sensor..after awhile the door ajar light would go out..and then when someone opened the passenger door..then the door ajar light would come back on..so i replaced the door sensor on the passenger side and it fixed the problem..i hope this helps

Sounds like a fuse: there is probably one fuse that controls the 'instrument panel'. Always best to check the simple stuff first.

If the switch is working, you can adjust the door, or some times the switch.
