Broken wiper fluid pump mechanism - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I turn on the windshield wipers in my 1980 C20, the wiper fluid pump always runs. At first I figured this was an electrical issue, but after digging deeper, it turns out there is a finicky mechanism which connects the wiper motor to the wiper fluid pump, and the problem seems to be in there somehow. I just can't figure out exactly how it's not working.

I made a video:

Any ideas?
