I am trying to locate the window door glass glide material that holds door window in the felt for 2003 Toyota Corolla: ? does anyone know how I can find one inexpensive.

Probably Dealer only, sorry to bear that news. Salvage yard felt would almost certainly be ate-up already for a 10 year old car, and regular parts-stores maybe can order it, but you would not be getting genuine Toyota material, it will be some aftermarket crap that you would have to trim to fit properly, not to mention the quality of the material is inferior from Toyota. I sound like I work for Toyota, be I assure you I do not. It's just some parts-houses will say, 'well this is close, it is for a (insert car) but with some trimming...."
