Hi...I give up...I have no blower for the ac. Fuses are good. Ground
seems good. Switch has no power going to it (can't get a test light to
work on the red wire on the switch). What else could this be? Shouldn't
the red wire be hot from the fuse box, then once you turn it on it puts
volts to the other wires based on what fan speed you need??? And the
wiring diagram shows the ac resistor (on the ac box in the engine
compartment?) in the wiring loop...I'm not getting any volts there
either...Does anyone have any suggestions...please???
