Default Washer Squirters Won’t Stop

I have a 1971 Trans Am. One thing I haven’t been able to figure out is that if I get water on the car in any significant way like a car wash or heavy rain the washer starts squirting and won’t stop until I unplug the connector. Otherwise it all works fine. Everything looks fine. I’m not a great electrician. How can I figure out how to fix this?

Wipe and wash work opposite to other circuits on your car. Instead of turning power on and off to work, the wiper switch supplies ground for wipe and wash. Power comes from the ignition switch being turned on.

Coil winding for the electro magnet used to turn wash on, is like the coil windings in a relay. Very little amps are seen on the ground side of the coils. Water is enough to complete the ground circuit if something in the wash wire or terminals is really close to touching metal (or a wire) that's already grounded ..

That's one possibillity that you can check by pouring water along the wire and connector (for wash) with the wipers turned on. Wiggle test on the wires might be enough to turn it off or on. Just depends on 'IF' it is water completing the ground circuit.

Moving the wires might do it 'IF' it's just a bare spot in them somewhere.

'IF' water makes it happen, I'd take the terminals out of the connector so you could plug them in seperately. So you could see IF it's happening in the wire or at the terminal.

That's one thought
