[DML] Re: Cleaning off heater core to improve airflow

["ksgrimsr" <knut.s.grimsrud@xxxxxxxxx>]

Dave S was right on the money.

I did have some debris on the evaporator screen that I vacuumed out 
which I'm sure helped a bit, but the primary culprit was the foam 
cover over the large rear hole in the box. The glue had probably dried 
up and a large portion of the foam block was loose and flapping free 
(exposing a large hole in the back of the box).

You have to be a bit of a monkey (long arms with a couple extra 
joints) to get back there, but you can feel your way around from the 
driver's foot well.

Thanks everyone for the tips and help with the airflow issue.
