    Afternoon,
    When I put my blower on to full I get pieces of foam (I think sealing foam) blowing out of the upper and lower vents (1996 300 TDI 90) has anyone had experience of this or know where the foam is coming fro ?, I'm stripping it down for a refurb and want to ensure I replace the degrading foam, I've checked the foam that is between the duct and the blower unit it seems fine, do the diverter flaps that send the air up or down have foam on them ? any assistance welcomed

    Foam in the following places
    Heater matrix
    Air intake(wing top to heater)
    Air to dash(heater to bulkhead)
    Flaps for screen to feet.(solid pieces)

    Can't remember if there is some where the off flap is(big flap closes the heater off for all intake of air)

    Camping mat. It dense so won't fluff/flake but is thicker. You will need to remove dash to get to the foam.
    You need to remove all the screws & the flap cable.
