      Question 2013 XC70 - Rear Windshield Washer

      So our rear windshield washer no longer pumps fluid.

      It started after we had some hail damage repair, and complained to the shop. They diagnosed it as the pump was going, since they were not responsible, said I would fix it later.

      Well the car was in for some other repairs and they swapped out the pump for us, the 2-in-1 that goes with the front pump.

      Well, it still doesn’t work.

      Is there something else I should be checking to help narrow down what is going on? Is there another pump somewhere else?

      I am 99% certain they dropped the headliner to fix the hail repair, not sure if there is anything routed in the roof that deals with that.

      Any help or insight is appreciated!

      First, use a light gauge pin, and ream out the spray orifices at the top of the tailgate. If that doesn't work, you may want to pull back the headliner and check to see if the rubber tube got pinched off somewhere.

      One would hope it isn't the 3rd option... that the rear hose has failed and is pumping fluid somewhere.
      Is the sound of the pump the same or nearly so in front vs rear operation? Or does the rear operation sound a bit, er ... constipated, which would support pbierre's diagnosis?
      Or the 4th possibility: could the rear hose be frozen?
      Good luck getting it sorted.

      It wasn’t clogged. Also the check-valve in the rear is fine. My guess is there is a check-valve closer to the pump that is clogged or broken.

      Any idea where that is?

      Well the pump sounds the same. I pulled off the rear trim on the lift gate and the check valve is fine there. I am guessing there is another check valve somewhere closer to the pump.

      Also it is not leaking.

      Do you have any idea if you can get access to the washer pump area if you pull the wheel and then pull off the mud guard that is there? If it means pulling the bumper I will just take it in.
