No Rear Defrost

I have noticed that my rear defrost doesn’t work, now check the wiring good, 2 fuses seem to be good (the one under the hood not to sure about) can see the cooper but idk. press the switch seems like it isn’t getting power has anyone had this problem that can help changed with a switch that worked in another DA

Does the button light up when you press it?
Also, do your intermittent wipers work? If not, the answer is a bad ICU.

The switch does not light up or feel like its getting power to it, and yes my intermittent wipers works

Oh, then its gonna probly be in the wiring or just the switch itself. I may have an extra, ill take a look when i get home if you want.

I changed it out with a working one but I don’t know why its not working…how hard would it be to just rewire it?

This same thing is happening with me. I have changed the switch out as well. Doesn’t light up, but everything else electrical works like it should. Sucks real bad when it rains.

Should the button click when pressed like the fog light button? Or just light up?

It should click and light up, my switch work on my other friends DA but not on mine…

All depends on your skills really. Probly would be a pain in the ass to get to some areas im sure though.

That’s strange, the second switch I got didn’t click or light up either. Maybe I managed to get 2 bad ones.

i got the same problem, but my switch works, it lights up and the wipers work. i dont think its the insulation

Update, Ran down the wiring no cuts, brakes, or cracks. switch works on my buddy’s 93. rear window wash replaced with a brand new one and fuses changed. Nothing Going to change the ICU and see what happens…

My new ICU came in this morning swapped it out and bam the rear defrost button clicks and lights up! Rear defrost is now working! Everything works

Was your defrost the only thing not working?

Yes it was the board wasn’t in as bad of shape as some others I have seen.

Probably exactly whats wrong with mine. Everything else in my car works but Defrost and the wires are good all the way to the front and i have replaced the switch.

Did you buy a new ICU?

Damn I got lucky! How hard was to repair them? I have mine which the board is pretty clean, everything works on mine except the rear defrost.
