Rear defrost doesn't work. Any suggestions?
Hello.
So earlier last summer, I changed my hatch shocks because the hatch needs to stay up to pass safety where I live. I ended up using Jeep Wrangler shocks. I don't remember what year I used, but I followed the thread that was posted on here a while ago.
The rear defrost worked earlier in the winter, but now doesn't work anymore. The red light on the switch doesn't come on either. I was going to switch the end caps on the old shocks to the Wrangler shocks, but I didn't end up doing that because the Wrangler shocks had the tabs so the wire could plug in anyways. A little after that, my rear wiper stopped working. It used to work sometimes, but like kind of stutter? If that makes sense? Now it just doesn't work. It's stuck in the bottom position. I've checked fuses, and they're fine.
I don't think the two are related, but just though I should mention that.
I appreciate any help.
Thank you.

And then I discovered the same problem as you.
What I ended up doing is wiring bypass wires so the shock does not carry the defrost grid current.
Because the stock shocks are conductive, the replacements are not.
The defroster light should still light up tho. And the rear wiper has nothing to do with this.

I did the same thing! Replaced my shocks with the Jeep ones.

My light does not come on, which I also thought was weird, which is why I checked the fuses.
Since you've done the same thing as me, I'll love to know what your opinion is on me changing back to the old shocks or bypassing the defrost grid current.
I appreciate you reply alot.
Thank you.

Whatever you do be REALLY careful with the defroster tab. If it comes unglued from the glass, you must use an electrical conductive epoxy to put it back on with. Most have a heavy silver content and are EXPENSIVE for what you get..AND they don't stick worth a hoot. They take a long time to cure as well and getting any type of tape or clamp on them is a real time waster...at least while the back hatch is installed..Let me know how you fare in all this..Thanks.
