new window felt/ window stuck

[85supersierra]

just installed my new window felt and now my windows wont move. i knew they would be a little tight for a while but the window barely makes it half way up then stops. I also installed new window motors and cleaned and greased the regs. any suggestions on how to speed up the break in time would be great

I wound up changing the felt out to some ordered from classic parts. The ones from rock auto looked the same but even sprayed down with lithium grease the window wouldn't move.

Following this..... thought I saw a thread about window thickness changing. I have same proble, new motors,regs and felts...... Lots of down, no up

To my suprise gm still makes these so I ordered them from the dealership. Had no problem. One thing you may want to try is to spray the fuzzies with some silicone. Really helps. Cuts down on the friction. These windows were not known for operating well. Any thing that you can do to help them will help.
