rear window very slow
 

The back window in my 94 Bronco is very slow if it works at all it seams to catch some,
were I have replaced the felts and gaskets? around the window, greased the mechanism but it is still very slow any help would be appreciated Thanks

Welcome to the site..

Could be a motor issue, more so if the ops are intermittent.
Felt, meaning all the window channeling is new?, or just the wiper strips etc? Sometimes new or aftermarket channels can bind the glass a bit. Easily seen if the glass is separated from the regulator and the up/down checked sliding the glass by hand.

Yes I replaced the window channels tat are on the tail gate they were missing and the one remaining was brittle the gasket around the window seams soft and pliable , but the window seams to bind some were but I am unable to see it?
