Basement blower motor

[prpickett]

I have a 99 Dutchstar and am having trouble with the basement blower motor. It works if I apply direct 12 v power so it doesn't appear to be the motor. I checked both leads going into the switch in the utility bay and don't have any voltage there. The furnace appears to be working correctly. Is there a fuse somewhere that goes to the blower motor? If not, where should I check for power upstream of the switch? Thank you,
Phil

I believe it works power wise off the furnace control circuit board. Your louvered air vent, stuck on with Velcro, below fridge has 2-3 fuses taped behind panel.
You already know about switch on water bay panel.
One of them maybe the supply for duct 12v fan.
Never had to check it out so as far as I know you are the first with the problem.

Phil:
Where exactly is the blower motor located? I also have seen the switch in the water compartment, but I haven't seen the blower motor.

In our O2 DSDP there was a fuse for the basement blower motor behind the louvered door underneath the reefer in the compartment that housed the heater. If I remember correctly, it wasn't labeled. It was an inline fuse just dangling down in the front of the compartment. For some unknown reason ours blew--replaced it and didnpt have any problems for years.

Mike if you go to outside compartment where you can see your water tank, this is for a gas coach, on drivers side lookup near ceiling of compartment there will be a foil duct thats coming from furnace.
Look inside the duct and you will see the 12v fan.
Some times people do not notice duct and force items up next to duct and can collapse the duct or cause the fan to turn in duct so the air is not force out into tank area the fan is just blowing side ways in duct.
