Check ignition switch, common problem.
get a new defogger.
Check driver left side kick space for a black control clipped onto electrical box.
where is the rear defogger relay located in a Toyota Camry
My 97 Buick defogger module is in the rear leftinside panel.
A defogger is the system in your vehicle that prevents your car windows from fogging up which prevents you from seeing out of them so that you can drive safely.

As most vehicle defogger controls operate in a similar manner, and as I'm not familiar with your make and model, this answer will be generic in nature. Rear defoggers generally draw a fairly large amount of current, and therefore that current does not pass through the cabin control switch. That switch controls a special type of relay [a time delay relay]. When you press the switch to turn the defogger on, an electrical pulse is sent to the time delay relay which closes, passing electrical current to the defogger grid. Within the relay is a timing circuit which, after a finite period of time, is supposed to release, and open the relay switch contacts, turning off the current to the defogger. From your question, I suspect that your defogger relay has FAILED IN THE ON POSITION. Usually, this failure is fatal to the relay, which must be replaced. I have a Buick Century wagon 1996, and I ran into this problem. Have you noticed if the defogger switch lights up when you hit the brake? If so, you have a bad connection somewhere. The center brake light is on the same circuit as the defogger, so you may notice that the center brake light does not light up when you hit the brake. So if this is what's happenning to you, you either have a burned out center brake light, or the defogger terminals in the rear window aren't making a good clean connection. They are located on either side of the window near the top. What I did to fix this was to solder a small piece of metal to the terminal that was not connecting and it was thick enough to make the connection. So the center brake light works, and the defogger now works exactly as it should. Hope this helps.
It is possible that the rear defogger does not work on the 2001 Hyundai Accent because the vehicle has a blown fuse or damaged wiring. The defogger might also not work because the wiring is disconnected.
Found out that there is no separate relay. The defogger switch has the timer circuit & relay built into the switch. Also, when there is a problem with the rear window not defrosting, check the electrical connector behind the rear driver side trim panel next to the rear window. You may need to remove the hanger hook screw to remove panel. The panel is held in with a plastic insert. I had to slowly pull the panel away from the car body. The (pos or hot) wire from the window grid goes to a connector behind the panel. Found the connector had overheated, and therefore had a bad connection. Had to replace connector.
demister is the same as defogger
The fuse for the rear defogger is located behind the glove box. Just had mine replaced.
