Thank you for the photo. This is supposed to be one but it looks much different from yours. How does it work? Is there one vacuum line for each half of the windshield or something else? Also, the knob or piston appears to be missing.

A Trico visionall switch is the most difficult part to find for any Cadillac in the early 30s. It took me 17 years to find one. And it’s not my first rodeo.

Steve, the knob portion looked the same as Wayne’s. It was two positions, and the back side I can’t remember. If you over tighten them they snap off...........just tighten them with your fingers.........even just a bit of torque with any tool will make them fail.
