That is too much for my brain cells. Only one pump for both systems? That would mean there has to be a split somewhere along the line to switch between the front and back. That is too much engineering. SO the question is, did the nozzles freeze up? Or did a hose come apart and now you are spraying the ground? Can you hear the pump when trying to wash - look at the inside switch/button?

Great information. The second line is for the rear washer. You're right, most aftermarket pumps have only one. In the same model year (2004) later VIN numbers (last 6 digits -127149 and beyond) went to a single pump which is A LOT for expensive than buying 2 pumps with the old design. Partsgeek has an OES(?) that arrived 2 days after I ordered it for $65. The Volvo dealer wanted $90. Hope this helps. OBTW, you saved me $200 in labor. Thanks.


Also, I had to PRIME the pump BEFORE reattaching the hoses to prevent an air lock in the pump. I know it sounds weird but after priming the pump, I immediately had fluid coming out of all washer nozzles.
