Rear window defroster not working? Why?
The switch for my rear window (hatch window) defogger isn't working right.

Normally, you put it on, it stays on for like 5-10 minutes, then goes off.

Now, I have to push it like 10 times before it goes on, and even then, it goes off again after about 20 seconds.

I have an 86 SC. What do you think the problem is? Switch? Wiring? Contacts in the back?

If it's switch or wiring, are replacement parts available, or am I doomed to have a permanently foggy and icy back window?

Thanks!!

i would check all the wires first but it sounds like the switch is going on it. i would look at junkyards for a used switch since there cheap there

Also make sure the two wires from the defrost grid are connected to the tabs on your hatch struts.

It's probably the switch,but I'd check everything.

Yeah, I have that problem too. The one on the driver side comes off all the time now, I'm used to always reattaching it.

But that doesn't seem to affect the switch light going on or off, it behaves the same way, just of course it doesn't defrost when the tab is off.
