Remove the RC Evaporator cover to verify the gasket type
is the correct version. The correct version should seal all of
the gaps preventing any air leaks. Leaks will cause moist air
to bypass the evaporator and accumulate frost. If the RC
evaporator cover is not the correct version, replace using the
table below.
NOTE:
Before you can remove the evaporator cover the doors
need to be removed.
