1-3-2-4 Posted June 9, 2011 Share Posted June 9, 2011 Not really that much needed now only just when it's dew on the window.. but I've figured now it's hasn't been working. I haven't used my meter on the defrost lines but anything else I can check before I do anything else? I'm going to assume the wires that connect to the defrost lines are under the cover part where the motor is for the rear wiper? Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted June 9, 2011 Share Posted June 9, 2011 I would suggest checking the fuse first. If the fuse is good, then using a multimeter, check the operation of the switch. Unlikely in my opinion, that your problem is with the defrost lines or wires on the rear glass itself. Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted June 9, 2011 Author Share Posted June 9, 2011 I will check the fuse but the switch lights up and all when you press the button. Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted June 9, 2011 Share Posted June 9, 2011 I will check the fuse but the switch lights up and all when you press the button. If the switch lights up, then I am thinking the fuse is going to be good. I guess you will need to use the multimeter to see if you have power at the wire grid on the back window, which is what you wrote already on your original post. Since you are talking about a rear wiper, I am thinking you have a wagon, not a sedan. Removing the tail gate inside panel cover is not difficult. Wiring will be in there. I don't think it will be under the wiper unit cover. Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted June 9, 2011 Author Share Posted June 9, 2011 it's all behind that cover? I've removed it before on a 95 so it's not hard at all. when checking with the meter where should my ground be? Quote Link to comment Share on other sites More sharing options...
danbennett2u Posted June 11, 2011 Share Posted June 11, 2011 Is this for a legacy? On our 95 impreza the wires at the top of the hatch under the rubber boot that connects body to hatch had been crimped to the point that most had broken, including wiper, defrost, brake light. Give that point a quick check, its very quick and easy. Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted June 11, 2011 Author Share Posted June 11, 2011 I will have to check that out Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted June 18, 2011 Author Share Posted June 18, 2011 looking at my service manual I printed out what about the relay for it? I noticed (or at least I've not heard it) the click sound when you press the switch from the relay. I'd have to check later. Quote Link to comment Share on other sites More sharing options...
Cougar Posted June 18, 2011 Share Posted June 18, 2011 Another thing to look for is broken wires where the wiring goes into the rear hatch. Quote Link to comment Share on other sites More sharing options...
1-3-2-4 Posted June 18, 2011 Author Share Posted June 18, 2011 (edited) Seems like the switch is no good going by what my FSM says in the background I only get continuity if I press and hold the switch down on the pins as shown in the manual which is 3 & 5 should I jumper the plug that goes to the switch to check?

1-3-2-4 Posted June 19, 2011 Author Share Posted June 19, 2011 Looks like its the grid lines looks like they may of had a tint on the rear glass... I have to get a close up shot Quote Link to comment Share on other sites More sharing options...
