Problem with my 96 GJC interior lights

Bad ground somewhere, perhaps? Check the battery to body ground first.

gil did pass the time by typing:

Is the cargo light turned on? In the 93 you just give it a slight push like the forward lamps and it stays on.

Other than that, you might have a bad illuminated entry relay. It's in the relay center inside the glovebox. (on the 93 at least) you remove a couple of screws that hold down the bottom of the glove box and the relays are in there. Relay is the one furthest right toward the passenger.

There's probably a mercury switch in the tailgate... make sure that it's not gotten loose and hanging at a wrong angle. __ Steve .

Thanks, I check for this relay in my 96 JGC.

Do you know where that mercury switch is localed?

It would be inside the rear door... you would have to pull off the trim panel to see inside. When the door lifts up, it causes the mercury to touch two contacts, completing the circuit. Your underhood lamp (at least mine) is a similar arrangement, but much easier to get to. Good luck. __ Steve .
