91 k1500 5.7. Just replaced the sprayer motor on the reservoir but the sprayers still didn’t work. I discovered the ground wire was crushed in between the reservoir and the fender wall in one section so I resoldered that section but they still don’t work. I can confirm that the motor does not have power to it because I unplugged the fluid hose and nothing comes out. I’m also having an issue when I turn on the wipers (by themselves or with the sprayer) they don’t end their cycle at the bottom of the windshield, they just stop whenever they want. I think the crushed ground wire may have shorted something or it could just be an old truck issue.
