Drivers Door Weatherstripping Deteriorating on 2007 Highlander

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.

See if a local pick & pull junkyard has it, or maybe eBay if no one locally has it. They charged me around 5 bucks each to grab one and I needed all four incl the trunk.

The part is the same between 01-07 models despite the different part numbers. However, they can come in a gray or ivory colour (except the trunk) so I would confirm what you have first or the seller before ordering. Installation was super simple. No shop required, it takes 5 mins to replace each seal with no tools required.

Ouch those weather seals are damn expensive new especially when need all 4. Hard to find good condition used here in Australia.

I'm still experimenting on fixes...For starters I slipped 5mm latex rubber tubing (EPDM sponge also works) inside to thicken the seal and better seal the gap. It works great. Don't use thicker with 3mm or 4mm probably sufficient.

For the deteriorate bits I've tried black bicycle tyre patches but they're not hardy or big enough. My next step is to try thicker rubber strips and proper vulcanising cement. Haven't had time...

Another solution is to buy 2mm thick sealing foam strips (like they use around windows or door jams). I'm not sure about the aesthetics or longevity though...

Thanks Boony!
Mine is just ripped a bit at the bottom center of the driver side door and, as you mentioned, i may just insert something in there to cushion it a bit so when the door is closed it doesn't feel/sound like it's been slammed.

Hi Highlnder_1 only just saw your message as overseas at the moment.

Yes these fit no problem but a few niggling issues for the OCD amongst us. The weather stripping creases where it wraps around the corner of the door frame so there may not be a perfectly tight seal in this area ...otherwise it's just aesthetic issue. Another thing is joining the two ends ... I first tried glueing but it was ugly. I then overlaid the seam with those patches used to repair punctures in bicycle tyres. Looks better but still a bit visible. Also the AE weatherstripping is thicker so the doors are harder to properly close. This improves overtime.
