Default 99 Navigator AC blower help needed

Lincoln and Navigator forums haven't replied so I thought I would post here. My AC blower stopped working. I have the Auto Temp Control panel. Pulled the plug on the motor, hooked up 12V and it spins great. Removed the regulator and checked the 3 wires coming from the loom and it has no voltage. 2 fuses and the relay are good. Is my next move to replace the dash control unit? Thanks

Suggest you verify blower sw assy is sending ground to motor.

Thanks Hanky for the reply. Turns out it was something in the dashboard control unit. I went to the junkyard and pulled one from a 2000 Navigator. Swapped them out and now the system is working.
