I don’t but here is a link to the thread
Recirc door isn't closing all the way. In ye olde days you just adjusted the cable or slapped the lever harder. Now? Not so much.
Recirc was open. Or At least the light wasn't on on the recirc button(switch).
Recirc doors seal both ways. One direction to keep indoor air inside. The other direction is to let outside air in. In older vehicles you could partially open for close the door. Newer vehicles are binary. Fully open and sealed or fully closed and sealed. In either direction they may not seal properly. It's unusual but it happens. An easy check is to just open you glove box and drop it down like you were going to change the cabin air filter. Any noise involving the recirc door or fan, etc should be more noticeable. Don't have our Bronco yet but this design is common in many cars and has been for years. Recirc off is when the leak would be more obvious. Which is the condition you stated you were in.
Interesting. Do you have a specific product you’d recommend? I just reinstalled my hard top today and used my 303 rubber seal conditioner and was wondering if there is a better solution? thank you!
303 Aerospace Protectant is probably excellent for the gaskets. That’s great stuff. Probably apply it to a rag so you don’t get overspray all over wherever you don’t want it.
