Okay, if the fan in the rear evaporator isn't running, it is likely you have
a blown fuse. You say that you checked the fuse...I assume you checked the
fuse in the dash board, but NOT the one behind the left rear panel under the
evaporator. Since I had this problem, I can assure you that those fuses do
blow on occassion and it will prevent the fan from running.

Different issue. In this case I'd guess that your fresh air fan SWITCH is
going bad. However, 3 speed? I thought all the later Vanagons had a 4 speed
fresh air fan (there is a  3 speed fan switch for the auxilliary heater under
the rear seat.)

As I recall that switch, it doesn't guarantee that you are actually getting
power to the fog lamps. Depending on brand (such as the Projectzwo ones) you
may have gotten a relay that came with the lamps. Check the connections on
the BACK side of your fuse box that powers that relay. You may have a power
connection for the power to the relay due to oxidation of the connectors. If
that isn't it check the grounding line for the fog lamps. Use a Volt/Ohm
meter (VOM) to check and make sure that you are actually getting power to the
fog lamps. If you are...you might have the simplest of problems, a blown
bulb.
