Run a power and ground from your battery to the prongs on the blower motor where it plugs in... if it's ok, it'll spin right away.

That's where I'm stuck at on fixing mine.. tested the motor and it worked perfectly.... and swapped in another HVAC head that's SUPPOSED to be functional (from a friend of a friend of a friend) and I still don't get the blower to kick on.

The control head clicks and I hear the valves working when I hit the switches, and I'll get ambient heat from the vents when in motion, but that's it... not a chirp from the blower motor..


Is there a resistor or something between the control head and motor?
