    This started about 6 months ago while it was in the shop for my gearbox overhaul. Nice, right?

    Anyways, the headlights, taillights and turn signals all work. However, the interior lights and the side marker lights do not. Anyone know what could be the issue?

    The fuse and bulbs were checked already.

    Thanks,
    Vince

    front AND rear side markers?
    Rears are disconnected when bumper comes off for service. Maybe forgot to plug them in? Plug just inside bumper.
    Interior lights a different circuit. LIghts in door jamb work?

    Do the side markers work when you use the Park Light button on the centre console?

    It might be possible, but I would imagine the mechanic I took it would check something that simple. I believe the lights in the door jam still work.

    I don't think they do, I can double check when I get home late this evening.

    Just an update on what works and what doesn't.

    Door jambs and interior dome lights are still operational. The side markers still do not light up if you hit the Parking Lights button.

    A member did PM me and told me to check relay 15A under the passenger footwell so still need to check that out yet.

    Do side markers work when headlights on?

    Vince, the park light switch on the centre console bypasses all relays. It can't be a relay (unless you have multiple problems). Also, the column control and console park light systems use a different combination of fuses. Can you confirm that the front and rear park lights don't work? If it's just the rear, then that comes back to a disconnected plug or wiring problem.

    So which interior lights are you referring to? Instrument lights and switch logo lights?

    Just to clarify: The centre console park light switch uses an additional fuse "16" in the passenger footwell, but I see that system still uses fuses "11" & "12" (which are labelled Left and Right). Can you confirm that front and rear and also left and right are not working?
