Multi function switch gone wild

[bigkak]

I have a 2015 limited

1 No rear wiper movement or washer spraying
2 signals and high beam work
3 front wipers work but does not spray when button depressed
4 front sprays when rear washer switch is activated
5 new signal lever installed. Same issues

Any ideas???

Not sure about the Expeditions, but most washers chose front vs rear spray by switching the polarity of the pump. Look at a wiring diagram.

Looks like you need a new switch.
