what is all on the rear wiper fuse

Interior lights and rear wiper are on the same fuse. I have the same issue. All indications are that there is exposed wire somewhere that is shorting out, but I have yet to find it.

i also have the very same issue and would like some advise

Same here! :) lol. I just bought an incredible good condition Jeep Cherokee and the interior lights didn't work. So I check and the fuse was dead. I put new fuse and will blow in seconds, but thos 1 or 2 seconds the litghs works. I guess the same cable that come out from the fuse box will go up to the roof and go all back to the rear wiper. For now, I will take + from the headpanel mini computer to feed the lights, until I will find the problem. May be with time I will disconect the rear wiper. May be the motor is the problem. If any have the solution pleas post here ! :)

Same problem here its not in the door i even changed the harness to the door.

I have same problem with my 04 Grand, any updates ?
