Hello I have a 2015 Silverado 1500. Back when we had that deep freeze my wiper pump stopped working. Since I had just bought the truck I assumed that the previous owner had summer wiper fluid in. After the thaw, double checking the fuse, and now putting in a brand new pump I still can't even get the pump to even make a noise. Any suggestions??!!

See if you are getting power and ground at the pump pigtail... I believe it is actuated by power, so ground should be constant and power should be switched, usually on the combo switch at steering column.

Sorry I had to button my truck up for work tomorrow and I don't have a garage to work in. Assuming its either not getting power or grounding, ie: the pump is not turning on what would be the next thing to look at? Apparently my low wiper fluid sensor still works since draining the fluid to change pump.

frozen washer fluid my guess. if so new pump will also be damaged..

in the cold north this is rare , since we never add water to the washer fluid.. I was in florida needed washer fluid had a tough time finding 30 below F washer juice...

Just chase the pigtails back...but most likely, combo switch...how does your cruise work?
