Has someone forgotten to put a filter in my heating system when they built it or serviced it, or does everyone's car suck up dead leaves, break them into small bits and blow them into the interior along with a load of dust??
That's normal. There is no filter/ mesh on the air intakes for the heater. I think Hanger111 used to do a pair of filters which simply clipped onto the intakes.
mine does it too - you usually get a rattle as the leaf hits the fan, then when you close off all the other vents but one, -kabam - leaf enters cockpit at 100mph!
