My rear window defrost doesn't work

have you tested the switch it could be your fault

There are 2 Plugs that go into the REAR Defrost. If one of them is off, then it will not work. If you broke the Electrical Track, then it needs to be repaired... They sell kits to do this at your local Automotive Repair Stores... Time consuming but easy to do.

it is your blend door motor

That is the wire you need, it should plug onto a pin on the window

It is doubtful you can repair this yourself so I suggest you take it to a Subaru car repairer.

check the wires where they connect and plug in on both corners of rear window...sometimes they break off and lose contact ....they can be reglued on using a special glue that will conduct electrical current through it...can be found at most auto parts srores...good luck....Lee

Start with checking the fuse then looking at the wire or wires connected to the rear window defrost to make sure they are still connected

Yeah, I'd think it would have lines, too, unless some new way of doing it that I'm not aware of. Maybe the rear window was replaced with a window without the defrost option. There should be a small two wire connector coming out of the back shelf near lower driver's side of rear window. That would be the defrost connector to the window lines (that aren't there,lol).
Well, good luck with that! I think there are aftermarket kits for rear window defrost, though.

blinkers sounds like the flasher unit is not working. It's located under dash. Also check for burnt out bulbs.
Rear defrost, or rear defogger?: Your defogger for the rear window would run off a relay, probably located in the fuse panel of your car. Often, the connections at the rear window get broke or disconnected.
Front defrost: does your heater blower work?
