    Hello I am seeking for help with my driver side door. When I open the door the dome light will not light up even tho the switch on the doom light is on “door”.

    The passenger side door does light up the dome light when open. Any solutions to get my driver door to work?

    Also automatic lock does not work when hitting the switch. Also only on passenger side door lock works with switch.

    Does the front overhead light turn on when you open the drivers side door?

    No they do not. Not sure if they are supposed to? Only when passenger side door opens the dome light comes on.

    Oh, Oh! Time to trade it in! LOL

    Seriously, Check your fuses first. Then, look at the switches and obvious wiring. Something may have come loose.
    Not sure about the door locks. If it doesn't work with the fob, check the battery in the fob.

    I'm guessing a bad connection on your drivers side door switch. Wiggle it with your hand and see if it comes on, it may be worn out or just dirty. Since your lights work with the passenger side it almost can be traced to the driver side door switch.

    As you can see below, those switches on your A-Pillar (door jam) that activate the dome light depend on the screw holding them on to get a ground. I'd confirm: tightness; lack of rust; and continuity through the switch.

    The following is assuming no weld nut, but a self tapping screw holds the switch in place. If it has a weld nut inside the pillar, disregard.
    I'd probably take the screw out/remove the switch, tap the hole with the head of a ball pen hammer to flatten the sheetmetal a bit where the hole is at, and then re-install the screw. Being a self taping screw, the hole gets loose the screw will no provide a ground circuit.

    Thank you. My dome light works just does not work when I open driver side door. Dome lights up when Passenger door opens. I’m guessing it would have to do with my drivers side door.

    Each door has a switch for the light. I was referring to checking the switch on the drivers side. It's the black "rubber button" looking thing on the vertical surface where the front of the door contacts when closed.

    A bit of an older thread I see, but I'm having the same issue where the dome lights do not come on when I open my doors (both driver's and passenger's). I have also been having the issue where the warning chime does not come on if I have left my headlights/parking lights on (I am thinking this is possibly a connected issue since I believe they both cropped up around the same time).
    In wiggling the switches inside the door jamb, I can sometimes get the dome lights to come on. So maybe pulling that black rubber boot will allow me to clean up that switch a bit? I feel like the ground wire is worth checking out as it has been mentioned that the self-tapping screw can loosen a bit over time. Where can this ground wire be located in relation to the door jamb switch?
    Thanks all for the help in diagnosing this issue!

    It is almost certainly the switch or the ground. You just need to get in there and see what's going on. The ground wire in this case is the bolt/screw holding the switch in place. Do you have a multimeter to check the switch for continuity?

    I do have a multimeter to test with! So it sounds like that rubber boot just comes off, and then where would I test to check continuity? I'm guessing that the switch itself underneath that cover is just a plastic push button type?
    I did check to make sure that they weren't just stuck. When I open the doors, the switch pushes out, but the lights won't come on unless the rubber boot is physically moved by hand.

    On the switch terminals. Sounds like you haven't used the multimeter much. Your multimeter should have a manual. The video I linked to says to use ohms, and that's probably a safe bet, but some multimeters may have specific modes to check continuity.

    I'm on the same page and tracking now. I guess I was thinking about testing the switch installed on the truck and trying to figure out if that were possible. I do have a mode on my multimeter that beeps if there is continuity. So I'm thinking tonight I'll pull both switches, and then check the continuity between the terminals when the button is not depressed (door open, circuit should be closed) versus with the button pressed (door closed, circuit should be open).
    If the continuity check shows that the switches are operating correctly, it seems like the ground issue would be the next thing to tackle. If the switch is screwed into my door jamb, and that screw is what creates the ground, I'm struggling to see how that could be failing. But maybe some kind of corrosion or debris that's gotten behind the switch is causing it to fail?

    yes..the screw grounds it...so the switch should have continuity open..and no continuity while depressed..you could pop it out and connected the wire to ground to

    Guess i need to resurrect this thread. Can anyone post pix of where the switches are located and describe how to remove them for testing/cleaning.
