Thanks Rudy.

I'm struggling with this because the bathroom, galley, and driver fans all work. 

The salon/living room heater is a toe-kick self contained electric cadet heater so it would not be a factor.

I'll fiddle around with the AH relays some more.  Does anyone have a diagram for the relay wire connections?  I hoped to see some common wire colors at the fans and at the relays but I didn't.  The wires feeding the fans are brown and blue if my memory serves me...I'll have to open that up again to verify.

You might try the #1 heat pump setting on the 4 zone thermostat (if that is the system that you have)
And set it as high as it goes. 

I set all of my zones to 90 degrees last night and for the first time since i owned the coach had the Galley AQH heater fan started working. Then working backward shutting off each zone one at a time found that the Galley fan was controlled by the #1 Thermostat on Heat Pump setting.
