Your 2005 has the newer 675 Aqua Hot with an electronic control board which showed the low voltage light.

When the zone that has fan coil fan(s) not blowing any air, please go to the heater bay and see what lights are on the board.  Report that info and we can offer more help.

The fans are powered from the control board or that power triggers a relay to provide power to the fan(s).  If there are relays for the fan(s), that was installed by Newell.
