Tried disconnecting positive and connecting the third wire to positive supply? It should be the parking position connection. If it's working, then check the unconnected terminals in wiper switch for positive out when not used and connect to it.
Ok so the water pipeline is from down only the wiring is from top
And I hav half oreginal wiring of the rear wiper should I get buy aftermarket wires and conect tgem to the half wires wich is oreginal?
