So a draft in the passenger side footwell has been annoying me for some time and now that we're getting to the colder months again, its starting become more annoying and the girlfriend is complaining about cold air constantly blowing on her feet. I finally took a good look under there and I found the foam seal between the top of the HVAC blower and the inside of the cowl for the fresh air intake has disintegrated pretty badly. Does anyone have a part number for a replacement or any good DIY fixes? I'm planning on tearing my HVAC box apart anyways to replace the door and add in way to mount cabin air filters, so it would be good to knock all of this out in 1 job.

 

Gosh, I would think that a quality weatherstripping foam would be an adequate replacement if having to remove that box and reinstall it.

I have used this "expanding foam" tape from Lowes on my trailer for a few things and it has worked well. This is what my mind went to immediately when I saw what you were looking at.



**there are other similar options that are different dimensions, lengths, and cost.
