Before you go through the trouble to take apart the dashboard to access the
evaporator, try 3 things first:
1) Make sure there are no leaves or debris built up on the screen on the
cowl where the fresh air intake is.
2) Make sure the evaporator drain hose is routed through the hole in the
floor board and free of obstructions by poking a stiff wire up from
underneath.
3) Find a dealer that uses B-G Frigi-Fresh automotive air conditioner
freshener. The stuff is supposedly "professional use only," but it is
basically an aerosol air freshener. Frigi-Fresh works very well at
eliminating stale odors from automotive HVAC systems. Put the HVAC system
in recirculate mode with the fan on high speed, and spray the Frigi-Fresh
through the interior air intake under the passenger side of the dashboard.
Be sure to protect your eyes in case you spray into the wrong duct or it
comes out through the vents. If you cannot find Frigi-Fresh, you can try a
moisture of bleach and water in a spray bottle or a disinfectant like Lysol
or Febreeze.
You may be able to find a product that cleans or freshens evaporators at an
automotive parts store as well.
Good luck!

Thanks again! I'll try #2. I tried Frigi-fresh already, used according to
the instructions it worked great for about half a day then the smell came
back. Next I emptied most of the can into it, and that worked for a whole
day before the smell came back. Lysol gave the same result.
If I can poke a wire up through there, can I squirt low-pressure water up
there? I'm thinking it's probably mold/mildew on the evaporator. It's not
a strong smell, and not rotten or really bad, just sort of mildewy and it
annoys me. I heard of a kit which would let one pump solvent up through the
drain hole and when it drained out it would take all the gunk with it, but I
never found one for sale anywhere.

If you can poke a wire up through the drain hose, you should be able to
squirt low-pressure water up there. I would not saturate the evaporator
housing because the heater fan and resistors are up there. I have also
heard of kits that are supposed to clean the evaporator but I do not have
any experience with them.
