Windscreen washermotor not getting power

[XC70Bob]

Diagrams come from a DVD I purchased back when I first got my XC70, at the time you could find them all over ebay.

It contained vadis and the electrical diagrams for V70,XC70,S80,S60,V50,S40/V40 from 2000 - 2005

The diagrams do go back as far as 1994/5 but I don't know how complete they are as some of the year 2000 are not as good as the later ones.

I don't know if these are still available.

Can you hear the pump motor running ?

If so then you may have blocked jets or the inlet filter on the pump may be blocked.

Short solution: washer motor had seized, repaired it, problem solved.


I'm starting to doubt my sanity.

I was convinced I did not get 12V in the plug to the washer-motor when actuating the stalk on the steeringwheel and the headlight wiper next to it also doesn't work, so a wire-break sounded plausible.

Removed bumper and cover under the front window to track the yellow-silver and yellow-red wires coming from the washer-motor all the way back to the fuse-box.

Once I had the CORRECT yellow-silver wire (there's more than one ), and poked holes through the inculation with a VERY sharp measuring-tip, wires turned out to be OK. Since the relays switch to ground when not used, you can't tell a break plus a short to the chassis in the wiring from correct working wiring.

The breakers didn't have any correct washer-motors (or better "pumps", mine has two outputs, one for the front and one for the rear window, the V70 T5 pump I found just had ONE output and a different plug).

I ended up opening up the pump that had drowned, make it rotate again and filled it with vasiline so it would work again.

So the motor was creating pretty much a short, but not enough to blow the fuse. Haven't (nor have the energy) to dive into the headlight-wiper-issue.

Making the washer-motor run again together with putting the headlights on the central heating last night to get the condensation out was enough to pass the MOT...

They (MOT-garage) only bitched about the different color blinking lights (that have been in there since I got the car over a decade ago).

Whatever...

I think the pump may have seized again already. Well, I did get it to pass the MOT.

It might aslso be that I didn't properly add the anti-freeze to the washer reservoir before the current freezing temps (minus 10ºC here, pretty absurd for the Netherlands, especially being a stone throw from the North Sea). I did add it (it should be good for -20ºC or so now) and thought it would mix enough by just pouring it in quite fast. But I did NOT actuate the pump to get the anti-freeze into the tubes, so maybe the tubes were just frozen solid.
