Wipers won’t shut off

[Winni Laker]

I have a 2021 Silverado 2500hd and the wipers won’t shut off.  They do adhere to speed control but when I turn to off they keep going regular speed.  Had to pull fuse to get them to stop.  Any suggestions?  It’s under the 36 months but 40k miles. Will dealer charge me tons or should I fix myself?

I haven't had this issue but I was recently driving in VERY heavy rain and the highest speed was pathetic. Later on the picked up and hit a normal speed...curious to hear if there is a switch issue...

I would guess it is a multiswitch.  I have replaced them in other vehicles that the same thing happened.  This should be the part number 45369DY.

Had a 2023 Yukon Denali that did that. Mice chewed a wire when my wife went for a month to the farm while she was taking care of her dad. 
her dad passed and his pickup had mi e that built nest in air filter area and caused it not to start

Update for someone else finding this thread, dealer wanted $135 to diagnose and no telling what to install. Bought this part # 84924354.  For 2021 Silverado 2500 HD and it worked perfect. All fixed easy install. Turn steering wheel up and down, remove 1 screw on left side of clam shell, pop top off, replace switch . Part was only $38

So it was the multiswitch.
