There is a break between the switch and the rear window. Check for voltage between the gate and the window as this is usually where the problem is. If that checks good (has voltage) then a lot of the time its the main bar on the grid has a break onit these can be fixed as dealer has replacement foil for the gris.
the blower control switch pulls out
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.
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.
Short in the window switch . Check for bare wires before ther is a fire...
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
if the demister does not work,you should check the contacts on the respective windshield or it also could be a problem with the relay
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)
A combination switch is the unit behind the steering wheel that hold the controls for the lights, cruise control and window washer.
