Use a volt meter at the rear windshield to check to be sure that it is getting power. If it is... repair any breaks in the window grid. If no power... check the fuse,the push button switch, or the wires related to the to this system.
i have run into this prob with my 2001 and i found out that just under the left inner door trim at the floor, peal the carpeting back near the fire wall.there will be a square wire connector going to the rear of the car. you have proabbly burnt a wire somewhere in that connector.
when you find the burnt wire, just run a fuzable link there instead .
hope this helps.
In my case the switch to the defogger was fried and had to be replaced. I would first determine where the problem is, then get a haynes manual and see how hard it might be to fix the problem yourself. If you can't do it then take it to the dealer.
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.

Turn on the ac if you have it.

In most cases controlled by rear window defogger switch
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 the rear of the car maby?

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.
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
