Default help?

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?

The door switch could be bad. Do you have a fob? If so hit the lock button twice and listen for 2 chirps not one. If you hear two chirps that means the GEM is not showing a complete circuit through the door ajar switches.

You can tell which one it is by probing the wires on your GEM for grounds.

When your door ajar switches are switched by shutting the doors they ground out wires that goto the GEM.

For the Drivers side door the Yellow/Black wire will be grounded when closed.
For Passenger/Rear Doors (on 4 door models aka SuperCab) it will be the Grey/Red wire.

You can test by setting your voltmeter to measure resistance and probe these wires and a known ground to see if you get close to 0 ohms. Obviously do this with the doors closed.

If any of this confuses you let me know.

Is the door ajar light showing up or just your dome light turning on or is it both?

If its just the dome light try moving the dimmer dial. Round dial next to headlight switch.
