Winsheild Wiper issue

[nkostop]

So I have a 99 Yukon denali and when I turn my wipers on they works, but the wiper fluid doesn't work, and also, when I turn the wipers off they keep going and sometimes stop in the middle of the windshield. I have no clue why?......Any have this problem and/or know how to fix it?

motor control board replacement for wiper control. tsb issued for it i thought. washer is controlled by same board mainly but could be a broken motor or switch. fix you board problem first and go from there.

Take the board out of the control module and resolder the largest solder spots before you do anything else. I think there is 6 of them. There is a sticky in the tech forum I think.
