Resistor pack is shot. You should be able to access it from underneath the
dash. I don't know about the Dak specifically, but it's normally right on
the bottom of the HVAC unit, or on the right side, accessible through the
glove box opening (once you remove the box). It should have a multi-wire
connector (usually four wires) to it. Unplug the connector, and the block
should unscrew from the housing.
I do not know where is is located exactally in that truck but there is
a a set of resistors coils that are in a air duct that allows the
selection of several speeds. They are known to burn out and it is the
first thing to check. They are mounted through the side of duct with a
connector on them.
