Windscreen washers gave up completely a few days back, lots of noise but no water from the jets. I guessed that the water was frozen. However, once the temperature had picked up a bit it wasn't much better and only 1 of the 4 x jets was really working.
I found a bit of fusewire and cleared the blockages and the n/side is now fine but drivers side nada. ended up removing scuttle cover etc, pulled the nozzle out and managed to clear it (bicycle pump!) but it is still not up to much. Also I notice that recently it takes several seconds for any water to reach the nozzles.
a couple of questions spring to mind:
1 is the connector in the pipe on the rhs of the engine bay a non return valve? (or just a connector) The pipes are well jammed onto it so I don't want to risk snapping it if no point.
2 what are the electrical connections on the washer nozzles for? (hopefully not to open valve when water is required or the bicycle pump won't have helped

)
I will be having another go at it tomorrow so i'd welcome a little guidance from those familiar with the system.
regards to all, Les
