Wiper Wont Turn Off

[zsmith2812]

2013 Silverado 5.3

I have read a couple posts about this but need some clarifying info.

My wiper will stay on even with the key off (had to undo the battery to turn off) I can go a higher speed but not turn them off with the switch. A couple post suggested the pulse control board that is under the dash. Has anyone changed one of these out? Any pics of what I should be looking for?

Welcome zsmith

Almost certainly it is the Pulse Control Board, which is located on the wiper motor.

Not difficult at all.

Suggestion: In the interim, just remove fuse (driver's side dash). Can be done without getting out of vehicle.

Google "silverado pulse control board replacement"

 

I stand corrected!  ...apparently design has changed in more recent years.

There is no pulse control board on wiper motor this year.

Maybe someone with experience this year will chime in.
