today I tested my interior fan and was covered head to toe in black powdered foam… I presume it is some kind of flap sealer in the air control system but now it is all over me… do I need to remove my dash
and fix this ?
Oh yeah, it’s the powdered foam from the flap that seals off the heater core when in the vent (no heat) position. Here’s what that entails. viewtopic.php?t=16068&p=80961
It’s a pain, but worth it in the long run.
The foam is possibly in there to keep the noise down, there are rubber flaps that do the sealing… Either way… bit of a pain. Drain coolant, remove dashboard and a lot of interior trim type of job…
