Pending failure of the regulator, it has started binding on itself.
210 Front Window "binding"?
I have a 97' E 420 and the front window is "binding". It will lower all the way down with no crunching or noise but when you raise it up it stops about halfway and you have to help it raise by pulling up on the front of the glass. Do you think this is a regulator problem or motor problem?
