If you have a first generation witch I don't know
if you do the AC is vacuum actuated and if you
have a vacuum leak and change of speeds it will
change where the ac goes according to vacuum leak.
The buttons on your dash for the ac along with the
cool hot setting run on several different vacuum
lines through the back. You could even have a
vacuum line disconnect behind the ac/ heater
control module. The button to turn your ac
actually cold is wired to relay witch in return
turns your ac fan clutch on to pump Freon though
the system and cool. It will say fan clutch relay
in your under the hood fuse panel. I even think
some second gens are like this too. The blower
motor speed is controlled by the the resistor.
It's on your fire wall plug in with like 5 to 6
different wires. But fun fact your real only need
the white and black wire at the resistor to run
your blower motor it just only works on high.
There are 2 there for that. But never wire them
together with out the resistor for them to go
through. Your hard wire them it will set your
truck on fire. Almost did mine because I bypassed
the resistor.
