I had this same issue on a 2000 model. After checking voltages at the rear lamps with no differences between the two sides, I then swapped the two brake light asseblies. The right side was not working when the lights were on and the brakes were applied, it still did not work when plugged into the left side, but my left side still worked when plugged into the right side. So, that left only the brake light assembly to be faulty. I ordered one off of Ebay, and replaced it with no other problems, except the left went out a few months later!! Try swapping the two asseblies and see if you get the same results.
No. Different shape.
The grand Cherokee does have four wheel disc brakes. The wrangler and Cherokee have rear drum brakes.

It sounds like you either have a bad headlight switch or the relay the controls your headlights has gone bad by sticking. you, Ray

Most headlights are not fused they are wired direct thru the headlight switch... Is your switch bad??
If your headlights work, but your tail lights don't, your bulbs could be blown. It is possible that you have a shortage in your car.
No, they are part of the headlight assembly.
check your fuses
