What is this Called? and where can i get it CHEAP?

So this isnt my car, its my Moms, but we Traded a 94 Grand Cherokee for it, and the Car is in really great condition. The one thing that is wrong/bad with it is, on the Drivers side that little peice of trim/molding/weather stripping thats between the Drivers window and the Drivers side Passenger window.. It is now Snowing here in Utah and so we want to fix the bad seal so theres no snow or cold getting into the car.. So can one of you please help me out and tell me what the actual name is for the peice, and where i can get it for a good deal.. Thanks in Advance.

I do not know what you call it either. I need the same part for the passenger side. Not available from dealer. We will have to scour salvage yards. Linda

Are you talking about the strip which is actually on the window, or the small piece on the bottom of window on the body?
