Car is a 2010 Fabia 2 1.2HTP. The rear washer is not working. I can hear the pump working and it is pumping as far as the rear wiper motor. I took the pipe off the back of the motor on the tailgate and water was spraying out. But when it is put back on the motor the pump runs but it does not spray. Is there some sort of valve in the rear wiper motor assembly. I poked a pin into the nozzle and it seems to be clear. Any suggestions?

Maybe blocked inside and pin not clearing it. Dont think theres a non return valve unless its inside the motor assemble. I would remove nozzle completely and try with a thin piece of wire. If its completely blocked I think you can get replacement nozzles.

Yes, pull the nozzle out with pliers and see if it sprays then.

If so, put nozzle into descaling solution for a while and then try to blow through it. If not, just buy a replacement for not much.

Pin is no good for unblocking, I seem to remember, because there's a right angle bend in the pathway the water follows, which you'll never clear with a pin.
