Sharing for others and for a question (see below). I have my dash out to refurbish and notice all the foam at the connections of the hvac duct is gone. I'm planning on running to the hardware store tomorrow to get some adhesive backed weatherstripping to use.
I also noticed that there are some large gaps in the ductwork from the main trunk to the defrost ducts (see circled area, ~ 1" gap). Is this normal or am I missing some sort of flex boot?
Last, the defrost ducts are both broken up where they attach to the bottom of the dash (see upper left arrow). The only thing I can think of is to try and epoxy them back together.
