Windshield washer pump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Thumper01 · 10-07-2013, 07:49 PM

I just swapped out my washer pump with a new one from Brothers. The old one was beyond repair. The problem is now when I turn on my wipers the pump comes on and stays on until I turn the wipers off. I do not have wiper delay just two speed motor. Why is the pump pumping when the wiper motor is on? Followed the directions which is very simple. Any ideas? Oh, its a '73 model if that helps.
Thanks
Sam

The mechanism is really dumb and over complicated. There are a Schwack of stupid moving parts in there that can stick. Pull the plastic cover and try to observe the function and lube the dry spots. I had the same problem and opted for the easy (and better approach in my opinion) which is to disable your pump and het a reservoir with an integrated pump. You can also get an 80s motor which doesn't have the integrated pimp on the wiper motor

Did I mention how stupid I think that setup is!!!!

You will have way stronger spray if you get a proper in reservoir pump!
