im pretty sure my rear wiper motor is dead but i want to test the wiring first, i know ive seen in multiple threads a link to the rear wiring diagram but now im having issues finding it, sifting through the pages and using the search bar, i feel bad for asking cause i know its here but could somebody please direct me to it? thank you in advance

WI-158 and WI-218 are relevant in the Wiring section. This should also help: http://legacygt.com/forums/showthread.php/3rd-gen-outback-4th-gen-lgt-bl-bp-wagon-hatch-223423.html

Inspect the wires in the two rubber boots that carry the wires into the hatch. It is very common for them to break. That's more likely to be the problem that the wiper motor.

i dug through and cant find section WI, but i did find how to test so that at least gives me positive and ground

ive pulled them back on either side and tugged on the wired but they all look and feel solid unless one is corroded inside out which is why the motor is suspect, id much rather fix wires

Download the .zip and extract it to your desktop or wherever, and open it with your favorite PDF viewer (NOT a web browser). Go to the Wiring chapter, all the pages in that section are WI-xxx (its the last section of the factory service manual, a.k.a. FSM)

You'll want to open the bundle of wires up. I'd almost bet you have a broken wire. "they all look and feel solid" is not a definitive evaluation.

There's a wiring diagram in this post that should be applicable to your 06.

Does the rear washer pump work? If it doesn't then fuse #23 might be blown. That, I believe, would disable the wiper motor as well.

The most likely wiring problem is in the harness going from the car to the hatch. In the wiring diagram, it's the wiring that goes from connector D35 to the rear wiper motor. There's only four wires in that harness related to the wiper.

The harness connectors (including D35) are in the cargo area, right side, slightly below the "D" pillar. The cargo area right side trim panel might have to be removed to gain access to the connector. (The other ends of the related wires are at connector D43 to the wiper motor.)

If you suspect the wiper motor, it can be checked at connector D43. There should be continuity between pin 2 and body ground.

lol i couldnt find the thread! but your title should be much more helpful :wink:

pump work, all lights work, antenna works, rear defog works, everything works except the wiper itself, until winter its fine, just annoying that its not in the home position, but i for one dont want to be driving a wagon in Wisconsin winter w/out a rear wiper lol

and thank you, hopefully this should do, what i was looking for was +/- wire colors

Hope you'll let us know what you find, and the fix . . .

will do...as soon as i have the time to dig into it....

 

[Zedhead]

Turn the Key on, turn the rear wiper on, check wiper motor wire terminals with multi meter. Is there power to the motor?

 

[CNY_Dave]

Did it seem to get slower and slower as time went by? Could just be it needs to be taken off, taken apart, and the shaft lubed.

didnt work when i bought the car in March, salesman swore it worked the day before.....

I've got pretty much this exact same issue. The rear washer pump works, defrost works, rear hatch lock works and the #23 fuse is good, but the wiper motor and license plate lights don't work. I found 6 broken wires inside the boot on the passenger side and soldered them back together. I've got about 13.1 volts between the #1 and #4 pins in the supply side of the plug at the wiper moter.
I'm thinking it's the motor at this point. How would the motor be checked? I'm still somewhat of a newbie to auto wiring.

. . . How would the motor be checked? I'm still somewhat of a newbie to auto wiring.

With the 4-wire connector D43 removed from the motor, check the resistance between pin #2 and pin #3 on the motor connector. If it's open circuit, then the motor is the problem. If it's somewhere around 5 - 20 Ohms (I'm not certain, but this is what I would expect), then I'd think the motor is okay.

Is the wiper motor currently at the "park" position, or did it stop somewhere mid-sweep? (If not known, then measure the resistance between pin #4 and pin #3 of the motor connector. If it's near zero, the motor is in the park position. See the wiring diagram.) If it's at the park position, again with the 4-wire connector removed, ignition On, and wiper control turned On, measure between the harness connector pin #2 and a good ground. Should be close to battery voltage. If there's no voltage, then there might be yet another broken wire. (Are you sure the broken wires were all reconnected correctly?)

As for the license plate lights, did you replace the bulbs?

2 months later lol finally got to test it, my luck to have the only outback on earth that its not the wires :/ sure enough motor is dead but it was my lucky day, found one on the bay for $50!

I guess anything is possible.

Can you describe how you tested it and concluded the motor itself is bad? This might be helpful to others reading this thread and not finding breaks in the wires in the flexible boot area?

with the car running and the switch on, using a multi-meter i put ground to black on the plug then red to the different wires, one is constant power for "ON", one is intermediate and the 4th i assume triggers the wiper with the sprayer (this one would have needed 2 people for testing) but since it doesnt work on full on or inter then can kinda guess what the last result would be.

i suppose im actually better off with the motor than trying to work on wires in that tiny gap!
