window problems

[BRIAN AND TERI]

I am having some window problems on my 1973 Boler.
The rear right window crank doesn't do anything anymore.
Is there something to adjust, or replace?
The other problem that just happened is the roller in the door window seems to be missing and it can't close tightly.
Where can you get parts, and how can you fix that?
Thanks from Kelowna, B.C. Canada

The window handle is usually attached to a splined shaft held in place with a screw in the center. It could be as simple as tightening that screw.
If not, remove the handle and see if the splines are worn. If there is wear, you could place a small piece of aluminum foil over the splines then replace the handle.
If the shaft turns freely with the handle removed without moving the glass then further work will be required and maybe parts.

vintage trailer supply has several different window operators available. That's the little gear box the crank handle attaches to. I've found a couple different ones at my local hardware store.
