No heat coming through the furnace duct in the bathroom

The last couple mornings I fired up the furnace after returning from sunrise. The furnace works great but there is no heat coming through the duct in the bathroom. From the basement - it appears that nothing is disconnected.

Suggestions on my next step?

If there is heat (forced air) everywhere except the bathroom duct, then there must be a blockage or air-gap between the heat box and the vent. Perhaps there is a kink or debris in the plenum hose? Fortunately, at least on my 3670, access to this area is fairly easy from the basement. Interesting that the bathroom vent in my rig usually gets all the heat and almost toasts our, ah, ahem, well you get the picture. Good luck.

I agree with RoadJunkie, In your rig, the rear wall of the basement will have to be removed to determine the problem and access the area. The flex duct is routed from the furnace under the floor to the crapper.

Bobby, is it no heat or no air flow?? Our BH came with the vent that you can close in the "reading" room.
