Interior lights pulse on and off when car is turned off

I have a 1999 Jeep Grand Cherokee Limited too. I'm guessing that's a computer glitch. Try disconnecting the battery for about ten minutes and see if that fixes it. I hope that helps.

Of you haven't already fixed it yet, check the wires inside the drivers door. The main power wire and ground wire have s tendency to break. You can tell them apart by the thickness of the wire. The ground is obviously black and the power wire is like a light pink with a blue stripe going down the middle.
