Rear heater and rear window break light not working

Sounds like a blown fuse...Check your fuse block for the rear window defroster...If it is OK, it might be that the leads to the window defroster have been broken by many openings and closings of the rear hatch.

If the problem is in the grid then the rear window must be replaced or the break in the grid found and repaired with a special kit. Get a 12 volt test light and probe the grid to see if it has power to it.

Did you check to see if the bulbs are any good? Is power reaching the bulbs? If not, why? Bad wire, bad fuse?

Until you find the problem assuming the bulbs are good, since the rear window brake light is good, you can always tap that hot line and run it to the hot of the bulb not working and now all will work.

ther is a break in the window grid. take a closer look

use a multi meter on each wire connection on the rear window or use a 12v bulb with the rear heater switched on and the key in the 3 position. if there is not any voltage or the bulb does not light the fuse will have gone. if it lights up then there is a break in the rear window heater which you can repair with a paint bought from any good car shop.

Check the fuse box. you may find a burn out fun specific to the rear window heater.

it works off heater fuse and has relay which you found and is good .the problem is a breake in the heating elements in the window. they can be fixed w/out replacing window . check each element in window w/ohm meter .put aluminum foil around the pos. lead on meter to check the wire.

first repair the ground to the right rear light, as for the heater it may be a switch or a bad contact

could be the light itself,the red brake wire that comes off the rear brake lights that feeds this stop light,sometimes things get shoved against this wire and its cut,or if it splits off in the frame,it could also be broken here too

Check the brake light fuse. The high mounted brake light (third brake light) is on a different circuit than the brake lights. Hope this helps.
