300 e w124 rear window demister
The rear defroster (demister) on a Subaru Legacy is built into the window. The lines going across the back window are actually the defrosters. If the vehicle is equipped with a rear wiper, the switch for this should be located below the radio and heater controls.
A pillar garnish cooperates with a center pillar to define there between a space which serves as a demister duct for conveying hot, dry air directed from a side demister nozzle to a rear side window.-...Yasar Arafath
demister is the same as defogger
Check the fuse, behind the drivers storage cubby (below and to the right of the steering wheel). Check the connection of the wiring to the rear window. Examine the demister circuit covering the rear window for any breaks. This is the usual place for any faults. A circuit board mending pen can be bought from electronics stores, that may repair faulty demister tracks. (Rover 400)

I would believe a demister is actually commonly know as a rear defogger. A long coil that loops the rear window that heats up to remove condensation caused by the interior of the car being colder than the temperature outside the car. Think of it this way: A glass filled with ice-water will have moisture on the outside of the glass. Imagine if you warmed the glass to the same temperature or higher than the air around it, the moisture would evaporate. The rear demister works in the same way. The lines going across your rear window is actually a single thin piece of metal with wires attached on either end. When electricity is applied, the metal heats up warming the window.
IT SOUNDS LIKE ITS THE REAR WINDOW DEMISTER (HEATER) you wont notice it working unless your rear window is fogged up or icy. CMK
In my corsa you need to pull the middle switch out. The one that adjust the power of the ventilator... It actually has a little sign of back window demister on it.
Yes
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.
The rear window motor on a Honda Odyssey is replaced by removing the cover screws, disconnecting the wiring harness, and unbolting the motor. A new motor can then be put in place and bolted in.
