    When I turn my wipers on the squirters come on and stay on untill I turn the wipers off. It does this at all wiper speeds. Got any ideas???

    sounds like a wiring problem. What year is your truck? I'd have to look at my diagrams, but if your switch was messed up or had a short somewhere it might cause that.

    1984 K5 I had to replace the wiper unit three months ago and it did the same thing with the old one. And if you have a diagram maybe you can tell me which wire controls the pump and I could just install a toggle switch to run the squirters...

    I don't have the wiring diagrams for a 84. Tommorrow when I go to work, I can get them at the shop. My service manual for my 74 give the following causes.
    A. Grounded wire from pump solenoid to switch
    B. Wiper switch defective
    C. Ratchet wheel tooth missing
    D. Ratchet wheel dog broken or not contacting ratch wheel teeth.
    E. Lock out tang broken or bent on piston actuating plate.

    C,D, and E are inside the pump. According to my 74 wiring diagram, normaly when you push the washer button, you send a ground out the dark blue wire to the pump. The other wire on the pump is the power. I'm willing to bet the wiring is the same on you 84. Either way, with a multimeter is should be to hard to figure out.
    Sorry it took me a bit, work has been all in my sh&t latetly.
