EUREKA Posted September 23, 2020 Posted September 23, 2020 Has anyone ever added defrost to the rear windshield. Is after market defrost even a thing?
omega_rugal Posted September 23, 2020 Posted September 23, 2020 AFAIK there are some aftermarket heating strips you glue to the windshield, but don't take my word for it
eaglescout526 Posted September 23, 2020 Posted September 23, 2020 This is from the back of the Comanche Accessories outfitter booklet. It was entirely a possible option.

eaglescout526 Posted September 23, 2020 Posted September 23, 2020 See I have always wondered this too because it would be nice to have after a winter rain storm when I go to leave in the morns. Sadly no one has said kit so I have now knowledge of how it was installed. I've often contemplated an XJ rear defroster.
EUREKA Posted September 23, 2020 Author Posted September 23, 2020 Found something, https://frostfighter.com/pickup-truck-rear-window-defrosters.htm?add-to-cart=1038 When it comes time to install my glass I will ask the auto glass shop what they think/know about adding rear defrost.
eaglescout526 Posted September 23, 2020 Posted September 23, 2020 Maybe that might work, I saw that coming when it said it wouldn’t work for sliders. You’d probably have to have two kits and trim them to fit and work on either side panes and hope that it gets warm enough to heat up the middle doors. But it’s not worth to go through the trouble for that
Ωhm Posted September 23, 2020 Posted September 23, 2020 Are XJs defogger relay (timed)/switch (3 pole) still available?
eaglescout526 Posted September 23, 2020 Posted September 23, 2020 I think there’s some left. Trick is getting the switches in good shape.
eaglescout526 Posted September 23, 2020 Posted September 23, 2020 84-91 defogger switch is different than the later years and is NLA 84-92 defogger relay, one left.
eaglescout526 Posted September 23, 2020 Posted September 23, 2020 Looked at later years and its funny that people possibly paid $200+ for a heated window relay. Good lord Chrysler.

Spinnakerblue89 Posted March 9, 2024 Posted March 9, 2024 I was wondering: Could the wire harness for the bed light be used to power a device for rear window defrost?

Not really. Unless you’re gonna cut the harness away from the dome lamp circuit. And the defrost also needs a timer relay so it won’t constantly be on.

Spinnakerblue89 Posted March 9, 2024 Posted March 9, 2024 That was another thought, since scrapyards seem to be chock full of Cherokee in my neck of the woods.

Its honestly worth a shot. I have an XJ electrical manual and could help guide ya through where to hook it up.

For now I'm just exploring the idea, I stumbled upon this thread as I was searching for ideas to fix the rear window- it has no handle. Luckily my local JYs all have a plethora of old Rangers and F150s also.

Spinnakerblue89 Posted March 9, 2024 Posted March 9, 2024 It sounds like it is an uncommon option to find today.
eaglescout526 Posted March 9, 2024 Posted March 9, 2024 I don’t think any MJ owner bought into it and if they did, those MJs are long gone now.
gogmorgo Posted March 10, 2024 Posted March 10, 2024 I was wondering a while back about using XJ centre console and rear heater ducting to run air up and back towards the window, or just warm up the space behind the seats. But I don’t often find a need for defrosting the rear window. Seems like the front defrost is good enough blowing air up and over the seats, and I’ve got my side vents (that normally blow on your face) aimed at the side windows if I need a little more air to keep them clear to use the mirrors. The heater is excellent considering it’s intended to heat 3x the space in an XJ. I just wish it had a combo floor and windshield position.
