I just got done going down a rabbit hole and ended up removing ALL of the dashbord/heater box...I changed all the foam out and cleaned it up for re-install and I noticed some openings on the back of the heater box, in the same ducting for the floor selection (the ducting that has ducts to either side and straight forward connecting to the center council vents....the dash was out about 10 years ago (I had it apart fixing mistakes from the first time...I should have supervised more closley) I am assuming theres ducting that atttaches to the openings, but I'll be damed id I cant remember what it looks like, where it comes out or where it attaches....anybody have Ideas, pics would be awesome.
Thanks

Mark
