FCP do a Pro-parts rear washer motor for under $10 US. You can by 6 for the price of one OE!

Pull yours apart, clean it, oil the motor, reassemble & test. That's what I did and managed to revive it for awhile.

To others: The lowest pump is for the front windshield, the upper pump is for the rear. This way as the reservoir level drops, the rear will go dry first and you'll still have fluid for the front, which is most important.

Didn't think you could disassemble these but there you go you learn something new every day. I'll give that a go. Thanks.

Oil it with leftover motor oil from your other car.

Hi Neil,

thanks for the write-up. Will proceed and do the test as you recommended once the car runs again :-)
Awesome, this forum. As soon as I've got something worth sharing I'll definately post.
Wish you al a pleasant weekend,

I really hate the Volvo 'engineers'. Dumb asses! Why do they design the rear washer motor into an almost impossible hole requiring the fiddling around of a short wire and impossible to remove power cable into an impossible to reach spot. They could have opened up the hole another 1/2" on the pump output side and it can then lift straight up and if the cable was 4" longer you could remove the cable once it was out.

Trying to get the stupid pump back in when you can't see what you are doing I managed to push the pump seal and rubber pipe into the water bottle. This in turn required draining the recently filled bottle by pulling the pipe for the front washers and allowing it to drain into a clean bucket. Pulling the filler pipe and removing the filter from the filler neck allowed me to use a spring loaded grabber to reach through the filler hole and recover the seal/rubber pipe for the rear motor. Lesson: apply a little vasaline to the pump input pipe so it doesn't push the seal in again!

Motor now runs fine and it dawned on me the lever for controlling the wipers was fine as the rear wiper still ran when the button on the end was pressed, just the washer motor did not run.

Tried to disassemble the faulty pump but only succeeded in breaking one of the tabs of the lower end. Could not remove the other to open the pump up and 12V and 6A would not turn the motor so I guess it is toast. One day I may try again and heat the tabs like I do with the headlight wiper motors to soften them and see if I can open the pump up and free it off. But if you can buy a Pro-parts motor for $9 why bother?

Lesson 2: run the rear washer motor at least once a month to keep it working!

Thanks to your tips on where the pump is located, I was able to find mine, pull it apart, clean the rotor, oil the axle and now all is well again! Thanks!

Neil, quick question:

How did you find out that the seal was not in place? With the pump in, I can't see the seal. Was able to top up reservoir to above seal level and it's not pouring out. Bit worried though, but should I be?

If your pump is tight and had resistance when you were pushing it in all the way, then you are good. The rubber seal has the tube as part of it that goes into the water to give you the water through the pump. If the seal is not in place your motor would be rattling around and you would not be getting water to the back.

Glad you got it sorted. You did better than me as I was unable to get the pump apart without breaking one of the clips. I'll leave it until another day when it gets a lot warmer, or I have time to get my heat gun out to it to soften the plastic. Probably do that when I have to take the headlight wipers apart to repair them again.

I got 2 spare Pro-Parts pumps that look identical to the original, for less than $10 each from FCP. They then put them on clearance a few weeks later for less the $6 each!

Thanks. The pump went in with some resistance the last couple of centimeters and I don't see any leaks so I'm probably good. Took a look from under the car at the bottom of the tank and I see only clear blue fluid (no loose objects in reservoir) when lighting with a flashlight so I am OK, I guess.

As for the repair of the pump: mine had only one plastic tab which was kind of brittle but did not break. To be sure, I added a tiny amount of glue to the edges when re assembling. Next time it fails, I am going for a replacement (used or new) anyway so no point in taking the risk of letting it fall apart :)
