Is there some sort of clip that needs to be removed before the window crank can be taken off? How does it come off?

There is a little retaining clip. One of the common window crank tools will pop it off. Otherwise you could use a small pick hook to grab the loop end and pull it out. Once the clip is off, the handle pulls loose easily.

You can also try sliding a rag or towell between the handle and the panel. You just need to know which is the "open" side of the clip. Do that a couple times and you will pop it off.

Got it! Thanks for the tips.

By the way, i have 2 original window crancks but for some reason only the other one seems to stick in doors. No matter what spring i use (i got 4of'em) Also the crancks are identical..
