Actually, I'm not sure what the correct name for the part is. It's the one piece nearly flat rubber stripping that is attached to the vehicle (not to the door) and runs around the entire door area along the base next to the "highlander" sill marking up the side pillers and across the top. A small 4 inch portion of that seal has deteriorated on the bottom next to the "highlander" sill marking. My local mechanic thought he could get the part, but hasn't been able to and doesn't want to replace it with a non Toyota OEM part of questionable quality. I was thinking of putting some duck tape on it but that might mess it up more. The only issues I notice with it aside from seeing it when I open the door is an occasional whistling noise when the vehicle is on the highway (that might be coming from some other seal for all I know since I can't be sure it's this one) and when I open the driver's door it makes what I would call a "honk" that I presume is air escaping from where the seal is torn. Is that seal or weatherstrip or gasket or whatever it's officially called available anywhere? I guess an auto body shop could do the repair but again, it might not be a genuine Toyota part and might deteriorate quickly or cause additional problems and auto body shops around my area tend to keep vehicles for days even for small repairs like this one that should likely take an hour or so I'd guess.
