There are two fan resistors, one for each fan motor.
Unless they both burned out at the same time, they are
probably not your problem, its more likely you have a
problem with the evaporator fan switch and its
associated wiring. See Bentley 97-140, Drawing 87-881a

> Is it inside the evaporator assembly?

Bentley page 76-9, Drawing 77-045 shows the location
of the resistors and the fan motors in the camper
models. They are placed between the evaporator and the
fan motor input so the airflow through the system
cools them. You should be able to test them to see if
they are "open" without dropping the housing, the
wiring all ends up behind the 'D' pillar.

I can email you the pertinent Bentley pages if you
need them.

Good luck,
