2014 GMC Sierra 1500 Power steer shuts off when driving on wet roads.

[Raymond Scott]

So I bought a 2014 GMC Sierra 1500 All terrain. In the last 5 months "which would be how long I have owned it" I have replaced the drivers door window regulator, Drivers door wiring harness and window motor again. And the transmission. Now if I'm driving on wet roads and hit a decent bump I lose power steering. Once the truck sits for awhile its fine. I took it in to a GM shop and had them look if maybe somehow the recall was reset when they programmed my tranny. They added the current updated fix for power steering and tried charging me for it which after some talking I got for free. They said if that doesn't fix the problem there is a bulletin that calls for going through wires to find an issue. I 99% certain there is a wire or censor that gets wet and when you hit a bump it sends a code and shuts off the power steering but I'm looking for some help from someone who has maybe already solved this to save me some time and money.
