I have a 99 Suburban that is having an issue, basically the washer pump will not pump at all, no noise, nothing. So after testing the pump (running voltage to the pump from the plug on the inner fender), it works, but not when using the wiper switch. I checked voltage at the same plug on the inner fender, and its like 1.5v, so I am thinking that it must be the switch itself (part of the wiper and cruise control combo switch on the column). But, at over $200 for this switch, I am hoping to try and do some additional testing to make sure first. I know there have been a lot of issues with the washer motors on these trucks, but I wanted to see if there were any known issues with the cruise/wiper switch stalk? Any help is greatly appreciated.
