Sorry to take so long but life seems to get in the way.

Pulled the bumper cover off again to get at the front washer reservoir.

There is only one pump. I disconnected the 2 wire power plug to it. 12VDC directly I get the windshield washer, reverse polarity and I get the rear washer.

Everything works so the issue is between the washer switch and the pump.
When I pull the front wiper stalk the front wipers go through the cycle as normal just no washer. So not sure which washer front or rear uses reverse polarity and how it is reversed (relay is my bet)

Hunting for a stalk from a local wrecker then we'll see.

thanks
