Was there ever a solution to this? I changed the motor (twice). Switched the lines and when I press the back button they spray fine. Changed relays. Fuses. I can't imagine the switch is bad because when i press it it makes a clicking sound near where the relays are. I'm at a loss and pulling my hair out. Help? Please!
:welcome: to the forum. Unfortunately, it looks like anyone with the problem has disappeared. Could be time for you to seek professional assistance, too. Someone skilled in use of a scan tool and diagnostic software could likely find the problem quickly and get it fixed for you.

Hi, had same issue. Now fixed, and quite easily.
Problem was: No front wind shield spraying......unless the wipers on and the turn indicator pushed up ever so slightly.
Turned out I replaced the turn indicator arm module for about $50 and 10 minutes with a 7mm ratchet.
It is listed as the "wiper, turn multi function switch".
Easy fix!
