Hi Al. I hope you don't mind m jumping in on this one. I've just bought an 09 FR-V and I have no water to the rear spray nozzle. The front is good and I hear the pump motor when operating the back, but no flow. I've had the tube off the rear nozzle and nothing. I need to trace it back to the reservoir/pump, but it appears to be awkward to access. Can I ask how you got to the pump? Did you remove the wheel arch liner? If so, was this fairly straightforward?
Any info would be much appreciated.
