Some rear window defoggers are filaments built into the rear window that heat up when the rear defogger is turned on. This type of window should not be scraped with an ice scraper.
in the rear of the car maby?
The fuse for the rear defogger is located behind the glove box. Just had mine replaced.
They make kits that are sold in most autoparts stores for repairing the broken wires on the rear defogger. Pretty inexpensive.
In most cases controlled by rear window defogger switch

This is normally a resistive heating fixed to the inner surface of the glass of the rear screen.

You can find a wiring diagram for the rear window defogger in a 1995 Ford Escort LX Haynes repair manual. The book is available at most auto parts stores.
Read your owner's manual. This information can be found there. No its not, it just shows where the fuse box is under the engine hood. I can't read which one is for rear wiper, or rear defogger. If you are unable to use the rear wiper and defogger, it is likely due to the fact that the rear window is down ever so slightly. I fought this problem for weeks until I rolled the window down and back up. Now the defogger and wiper work!!!
It's in the top of the rear window, it almost looks like the defogger wires, except it's not a straight wire. Note: If you are having FM reception problems, especially when the rear window defogger is on, it could be that one (or more) of the defogger wires are broken. It'll be in one of two places. The Windwhield or Rear Window. It's a wire inside of the glass. Hope this helps. tj
Not sure about the '76, but the rear window defogger switch on my 1970 Coupe is located at about seat level on the left side of the center console (tunnel) cover. It is about 6" to 7" off the floor and just under the dashboard.
