98 V70 AWD Rear Washer motor Rep'l

Post by **rmmagow** » 29 Jul 2014, 13:38

Looking for the rear window washer motor. From some googling it looks like I should be able to pull the failed pump from under the hood. I have removed the filler tube and cap, see some harness wiring. Do I just fish around there, pull out the pump and put in a new one? Got the pump so I'm not into monster diagnostics yet. Pump never made any noise at all.

I don't know if I am using MVS search function correctly. It returns a lot of useless info based simply on the words entered, not contextual like a google search.

Thanks Much

The rear window washer motor is right next to the front one on the bottle in the engine bay. Just be sure you have voltage at the connector.

On mine it is located lower on the tank, between the tank and the fender above the wheel well but that is on a '99. I just towed the car off today or I would have a real clear picture since the whole fender was ripped off of it.

What a PITA this is turning out to be. I've got some questions about the flow of things.
My front washers and the washers for the headlamps seems to work OK. I replaced the rear washer motor and still have no rear washer.
The line coming off the rear pump terminates at a three way connector. Apparently this three way connector is also directional.
Here's what I am experiencing, washer line off the pump to the three way valve. The "T" part of the three way valve has a short connector to a filter, the filter connects to another line which leads to a hard line going to the rear??. Filter is clear, blowing into the filter and no air flows at all. Almost like it is firmly blocked. The third side of the T connector I have open to atmosphere since I think it is part of a venting setup. There is another line that I have coming off the very top of the washer bottle and this too I have venting to atmosphere. New Rear washer motor runs OK, old didn't.
The squirter at the rear window, I can get it loose but can't figure out how to actually remove it to see if the line itself is clear.
The three way connectors that turned out to be three way valves kind of got me screwed up. I'm wondering if there is something else in line going to the rear that I need to check.
Thanks for reading and thanks for any guidance.

I solved this on a 95 850 by bypassing the 3 way thingy with a straight connection. It prevents gravity flow of water back into the bottle so squirting takes place immediately.
