Actually, the 'switch' is an "analog" variety that is an variable attenuator with the regulator itself as the 'heat-sink'. Energy is either pass through (high speed) or lost in the regulator as heat (low speed).
Hope that's not too technical . . . but it's how the blower reg really operates.
Ok, Eric . . . if all is connected and you have
verified that voltage from the N22 unit (in the dash), the blower should be on. The higher you set the voltage from N22, the faster the blower should run.
If all is connected properly, sounds like the reg is bad??
