Windshield Washer Pump Won’t Stop

Q: Windshield Washer Pump Won’t Stop

Early on in the restoration of my 1968 convertible I replaced the windshield washer pump because it was leaking. As a lot of restoration projects go, the car wasn’t put back together and run for several years after the install of the pump.

I later discovered that when I started the windshield wipers and then then pressed the button to start the washer that the washer would start but not turn off unless I turned off the windshield wipers. Now every time I start the wipers the darn washer pump goes on without me pressing the washer button.

I thought my windshield wiper/washer switch was broke so I replaced it with another one purchased at a swap meet. Guess what? The washer pump still activates when I turn on the wipers.

Any help would be greatly appreciated.

A: I remember my birds doing this in the 70’s, and part of the problem was the gear was worn, or the position of the pump needed to be adjusted slightly. There’s not really any room to adjust much, but somehow I got it working again, I believe it was purely a mechanical thing, not electrical. It’s been a long time, and I am being rather vague, but it’s all I’ve got for you.
