Not sure about your car but on my KIA the dome and rear gate light have switches on the light assemblies themselves for on/off all time/on with door. Check to see if you have same. Also, there may be another "dash" switch, typically on the dash dimmer switch which may be turned all the way from dim to off. Check your dash dimmer switch. Relays are typically in a fuse box under the hood.

SOURCE: 2003 dodge caravan won't start

My 2003 dodge caravan would not start after driving about 1/2 hour. I stopped for coffee and when got back in to start it started I switched gears and it stalled. I tried to start again switched gears then it started but only for 2 sec. No clicking, no cranking sound just would not start but battery functions were great. Spent 2 days with a mechanic who could not resolve so sent to Dodge. After a day of putting wires back and checking out the problem they said it was the computer. Said that it was bad and could be replaced at no charge due to malfunction. Yes, it worked fine afterwards no more problems. They also said that some of the computers are found to be defective like this one so I hope this helps you in the right choice to have the dealer check it out if you are unable to get a computer reading and there is no obvious short in the system. Free sounded very good but as you know there is no such thing as really free as they got me for other things $350 worth. ouch!

SOURCE: No headlights, or dash lights.

check the ground cable at the battery , youll see a break in the ground wire at the battery box, check to make sure the bolt is tight and not corroded (the break is the ground for most of the lighting )

You will need to test the Body Control Module, it controls the lights.

Yes they do but I would rather think you have a bad battery cabe connection to the system, sometimes the battery cable corrudes and you can't see it try replacing the cable ends and the connector ends espically if they are by the battery.

2009g6 dome light comes on all by its self why


The dome lamp switch has 3 positions: DOOR, OFF, and ON. When in the DOOR position, the dome lamp operation is controlled by the body control module (BCM).The ON position provides a ground for continuous operation. Ground is provided at G302. The OFF position turns OFF any dome lamp operation. The courtesy lamps, may be manually turned ON by placing the instrument panel (I/P) dimmer switch in the DOME position. When the dome lamp switch is in the DOOR position, the dome lamp will illuminate when a door is opened. When a door is opened, the courtesy lamps turn ON. After all the doors have been closed, the courtesy lamps will remain illuminated approximately 10 seconds after the last door closes. When the driver places the dome lamp switch in the OFF position, the dome lamp will be disabled.

Do you hear any chimes when the light comes on ? Door ajar switch problem , maybe . Picture of car with door open light lit on the instrument cluster ? When does it come on , when driving or sitting still or both ?

You mite want to take it to a qualified repair shop and have it checked for DTC'S - diagnostic trouble codes .
DTC B2555 05: Passenger Compartment Lamp Control Circuit Short to Battery or Open
The body control module (BCM) applies battery voltage to the courtesy lamps through the courtesy lamps high control circuit. When any door is opened, the door ajar switch contacts close and the BCM receives a door-open input. If the BCM receives a door lock or unlock input or a rear hatch open input, the BCM will activate the courtesy lamp high control circuit, providing battery voltage to all of the dome lamps, reading lamps, rear compartment lamp, and vanity mirror lamps. In the event that any of these lamps were to remain illuminated for more than 20 minutes with the ignition switch in the OFF position, the BCM will deactivate the courtesy lamp high control circuit to prevent a total battery discharge condition.

Do you know how to do basic automotive electrical testing ? How to test inputs and outputs of a control module ? in this case the BCM - body control module ? Find wiring diagrams at

Interior lights


This is both a courtesy and safety issue on many high end vehicles. The light from the interior lights can cast enough light to get to front door and possibly show dangers in your path. And after first getting into you car and starting it, you can check the back seat for any unwanted hitchhikers. As for the 10 minute timer, I don't know if this can be adjusted. A Chiltons/Haynes repair manual for you car may have that answer, or, the Buick dealership shop foreman. Best of luck.

The tailgate will close and lock but the interior dome lights won't go out and the instrument panel says the tailgate is still open.., please help !!!


The little switch that gets pushed in when door closes is faulty. Once this is replaced you should have no further problems.

Dome lights won't turn off


Been having a problem with the dome lights on a 99 chevy blazer. Still can't figure out what the problem is. There is a dome light overide button located under the dimmer wheel. When I push the overide button in the dome light goes off, but when I open any of the doors the dome light will not come on. When the overide button is out the dome light stays on all the time and will not turn off even though every door is closed. I checked all the pushbuttons and everything tests good. Has anyone had this problem and know how to fix it?

Dome Light (switched circuit now working) Shorted it out


Why didn't you hook into the entertainment system (radio ) ?
The one that turns on when the door opens is controlled by the BCM -body control module .You probably shorted out the transistor in side the BCM .
These lamps may be manually turned on by placing the interior lamp switch in the ON position, or by opening a door.
• The Dome Lamp
• The Rear Compartment Courtesy Lamp
• The Rear View Mirror Map Lights
The inadvertent power control circuit of the BCM supplies battery positive voltage to the dome lamp and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps. The interior lamps receive a ground at G401 or G403.
If the driver inadvertently leaves any interior lamp on the BCM will turn it off after a 20 minute time-out.
The courtesy lamps will normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to the interior lamps for the theater dimming feature. The courtesy lamps will also turn off immediately if a door lock command is received with all the doors closed, or if the ignition switch is turned to the ON position.
