it seems that the rear defrost isnt working in my truck. could this be one of those quirky chrysler things that is just known to go bad after like 7 days? havent had too much time to look into it as of yet just wanna get a starting point. switch? fuse? some of you guys know this stuff better than i know the back of my hand...!

thanks in advance

If it has had tint on it before the defoster may have been scraped of during tint removal.

I had a bad wire on my 97. It was were the wire loom runs from the body to the hatch. Mine was easy to find because my rear wiper and plate light didn't work either.

beach dude

yeah im guessing wire also. i looked at the wires that are on the window and all looks good. my plate light and rear wiper work.

Check continuity on the grid. If you don't have it then work back to the wire at the hatch. When I did mine, the wire was completly severed inside the insulation past near the commector at the top. I only figured it out because I just decided to pull the wire out and it started falling apart.

Good luck.

beach dude

is that where the back hatch and the body meet? and do i have to take the whole doo apart to get to the wire harness there??

beach dude

alright. afte further looking at the original issue ive found a wire in between the hatch and the body worn (black w white stipe). now when replacing the wire do i need to do the entire wire? does it run the length of the body of the jeep? is there a harness that im going to need or is it just the wire itself? sorry for being a dumbass im far from a mechanic!

Just replace the wire. The rubber sleeve between hatch & body, Doors & body. Are where most wires become worn. And usually the first place I check (along with using a volt meter.)
