I am attempting to remove the rear heater, but can't quite figure out
how to remove the plastic cover.  I have removed the screws, but can't
see how to clear the short air duct on the front side.

Earlier this year when I tried to use that heater it filled the cabin
with the unmistakable smell of antifreeze.  So I assume that either
the core or the valve is leaking.
