Pump is working as the rear wash jets are working
Pull switch forward for fronts no pump noise and no water
Hoses are connected
Why are the jets only working on rear and not front
Only 1 pump as I've removed washer bottle to check

The single pump changes between front and rear jets by reversing the polarity of the electrical supply to the pump.

Possibly there's a problem with the switch.
.

Scrapyard it is again then

Before you do that, run some temporary cabling from the wiring connector to the pump, to reverse the connection.

That way, the pump should work (to send fluid to the front screen) when you press the stalk ... and wash the rear screen work if you pull the stalk.

If you can now get the pump to work the rear washer by pulling the stalk, then you've proved that the stalk is okay and the problem must be the pump.

If the above "works" .. then the pump should not work when you press the stalk.

My money is always the pump.. since it sits in the crud and dirt and is immersed permanently in washer fluid. It has a harder life than the stalk... so more likely to go wrong.
