    Default Lost my interior lights

    In the process of replacing a light in the truck, all my interior lights stopped working. To be clear:

    My Instrument cluster lights up and works, the radio, the AC control, work also. My turn signals are fine but seem to be running at a lower power, the head lights and turn signals work.

    What does not work is the map and dome lights, and then my third brake light with the cargo lamp, and the courtesy lights in the door panels.

    I checked all my fuses with a mult-meter and they all beep out fine showing the signal is going through. I made no changes to any grounds and confirmed that my grounds are fine.

    I heard about some sort of switch in the doors that might trigger the courtesy lights? not sure about that and never touched it.

    I am kinda lost at this point.

    The switch that controls the lights is in the door latch mechanism. I have often seen door pins failing and causing the door to sag slightly. Eventually the latch mechanism gets beat up enough that the interior light switch no longer works. Do they turn on when you open your passenger door? Does the third brake light not work? or just the cargo light?

    If this happen while the new light was being installed, it must be a problem caused by the install.

    99% of the time it is a blown fuse (or two).

    Yes, it could be some other part of the circuit (wire, switch, burnt ground); but, the fuses are there to prevent damage. If the circuit was protected by the correct fuse size, nothing but the fuse should be bad.

    Unless, you accidentally cut a wire while doing the install.

    Is it possible that you accidentally turned off the interior lights?

    What light were you trying to install?

    I was installing my new LED under hood work light to the factory under hood work light harness that came with the truck (My model/year has a under hood work light).

    What does not work is:
    • the map
    • dome light
    • third brake light with the cargo lamp (Cargo light not working) brake light works
    • Courtesy lights in the door panels
    • Glove box light
    • Ashe tray light





    • None of them look burned out, no smell of an electrical burn, etc
    • No fuses are knocked out (I checked them with a Multimeter)
    • The door lock clamps/motors/ etc were replaced 6 months ago when I fixed my automatic door locks.
