After 60 years a common problem is that the window switch action is either erratic or not-at-all. This was the problem I found when restoring my ’49 Coupe de Ville. After searching for NOS parts, I decided that there must be a way to rebuild them.
Start by depressing the four spring retainers and pushing them out to where they can be pulled out, as in the photo below.
With the switch body out, carefully push the plastic pivot pin out. This pin can be easily broken, so be gentle with it. With the switch apart, the components can be cleaned of the dirt and corrosion. Re-assemble with the curved spring contacts as shown in the photo below. Re-assembly is simple and locked in place by inserting the four spring clips.
