My air conditioner works fine, but only on high (lots of air). Doesn't seem
to blow at all on lower speeds. As I don't know how these things are wired,
which should I replace, the fan switch or blower motor?

Thanks for any input.

Fan resistor. Has three or four 4 wires on it, mounted in the duct coming
off the heater box. You could have given us the year of the truck:)

Sorry! It's a 94 F250. You say it's IN the duct? This means access from
inside the cab? Any idea where to begin the disassembly?

And THANKS!

OK, found it. For future reference, it's located in the engine compartment
attached to the evaparator (square box next to blower). The easy way to get
to it, is to unbolt the vacuum cannister (big bulb thing with vacuum lines
atached) under the wheel well. 3 bolts, easy to get to. After that, simply
unscrew 2 wheet metal screws and remove the unit. Hardest part was to unlug
the harness. (use 2 screwdrivers to pry open the keepers). It's important to
take the part to Ford (Auto Zone etc doesn't stock it), because there is
more than one available. HTH somebody else.....

Make sure the blower spins freely and doesn't drag

The resistors usually burn out because of the high amps the blower is
pulling
