Put the dome light switch on door located on the headliner to the side of the light
By pass the door mode. The Dome light should have a 3 way switch OFF - Door open on - Constant on Move the switch to the off mode, and light should not come on when door is opened.
See if the button in the door jam is stuck and put WD-40 on it and work it in and out, and of course check the light bulb.
Most likely the fuse is blown for the dome light on the Silverado if the light doesn't come on.
If you push that button, the dome light inside of the truck won't come on when you open the door.
The door jamb switch normally completes the power circuit to the dome lamp when the door is open. When the door is closed the switch opens the circuit, removing power from the dome light. If the switch is dirty, defective, stuck pushed in, or disconnected from the wiring, when the door is open the switch does not close the circuit and the dome light remains off as if the door is still closed. The headlight switch provides an "alternate path" to close the same circuit and allow power to the dome light. I had the same problem on a 1997 Chevy C1500 pickup truck.
The dome light switch has 3 positions. Off-On-On when the door is opened. Put it in the proper position.
I have an '03 Kia Sorento. When my (center) dome light over the middle seat quit working, it was a diode in the system; replaced under warranty, now out again!! It now works when the key is on, and you turn it on from the dash dimmer switch, but not when you open the door; only the far back one comes on. The front map lights DO NOT come on with the door open.
The bulb could be blown.
sounds like GEM mod. is bad
is the switch on the dome light set to doors! if so, one of the door switches are stuck. spray all door switches with a good lubricating spray. and push on buttons with hand to free them up. if not that, then one of the door switches are bad. or the dome light bulb is burnt out.
There should be a SWITCH at the dome light! If not, remove the fuse from the fuse box above where your gas pedal is. OR: Simply remove the BULB from the dome light. duncanw.
The dome light switch on the dash is on.
