Re: Windshield Washer Help

If it is leaking, that is not good. The switch itself only provides the ground circuit for the pump and washer. There are two sets of plugs on the washer/wiper unit as you found. If your switch is loose on the dash it can make things quirky. What I do and some others have done and is an easy modification is to install a S10 blazer washer reservoir in the old bottle location and call it a day. I make a harness to connect into the old washer plug so it uses the switch like the factory style. I also make new washer lines to delete them from inside the cab. If something goes wrong, quick trip to the parts store and put in another pump. Easy peasy...

Here is my thread from 2016:
