1993 GC, where is the interior light switch located for the rear liftgate? I'm assuming its in the latch mechanism because I can't find a pin switch or a contact switch anywhere. I ask because I've been having an issue with the interior lights flickering while I drive the Jeep, and none of the doors or causing the problem. When I lift ever-so-slightly on the rear gate, the light will come on. I noticed both bolts that hold the rear latch in place were missing and the latch was just kinda slopping around in there, so I put in new bolts. (one hole was stripped so I had to finesse a nut on the backside). I haven't driven the Jeep yet so I don't know if it fixed the issue, but at least the light doesn't come on as easily.
Ummm, well ok, but you're only half right. Yes, there is a light on the roof just inside the rear hatch area that can be turned on and off by pressing on the light lense itself. BUT, the light will also come on when the rear lift gate is opened and will shut off when the gate is closed, so there must be a switch on the lift gate or in the latch mechanism as well.
Yes, I understand the light can be manually switched on and off by pressing the lense switch, but that is not my question. On my Jeep, a 1993 Grand Cherokee Laredo, the interior lights will come on when the rear hatch is opened and will shut off when the rear hatch is closed-- there is no NEED to press the lense switch, unless you want to override the light. However, even if you have manually turned the light off, once the vehicle is started it resets the switch. So my question is, is there a switch in the latch mechanism that turns the light on and off when the gate is opened/closed? Seems there must be because I cannot find a switch anywhere in the door jambs or door sill.
Your best bet would be to take the rear hatch cover off and see what you can find. If you break any of the plastic retainers you should be able to get a package of them from Napa for a couple bucks. AFter you take the cover off you'll be able to see what is going on inside. I would check the wires inside the rubber boot that runs from the body to the hatch, if I remember right your GC falls in the years that they were using some stiff wire and people were having trouble with the wire breaking inside the insulation. Hopefully you have access to an OHM meter. That will help you trouble shoot your problem.

take off the rear plastic that covers the back hatch on the inside. Lift the hatch up and look at the latch mechanism. if you look around on the passenger side up inside it you will see wires that plug into it. disconnect them or replace the switch that they plug into. some people fix them, I just unplugged mine. very common problem.
OP, I hear ya! I have been ignoring the same problem.. I go down the road and the interior lights keep flashing on and off and the V.I.C keeps beeping and displaying rear hatch open every time the rear hatch moves over bumps causing the jeep to think the rear hatch door is open. AM I correct?
Now I to can follow the above post and take care of my annoying problem , Maybe even take the tape off the front cabin light lens cover that I put on there so I can see at night with the interior lights flashing on and off.

I think I fixed it, I drove the Jepp around quite a bit tonite and never saw the lights flash once. So, I guess I answered my own question, there must be a switch in the latch mechanism and the loose latch was causing it to freak out when the gate moved. Its good now.
if you have the hatch open with the lights on you can press and hold the rear lens until the lights go off. it will make it so when you open the hatch the lights do not come on. then if you press and hold again, they will turn back on.
