Hi Scott,
We have a 2000 Patriot Thunder, with a Hurricane.
There is a front zone & back (bedroom/bath) zone. Each zone is controlled by a 2-speed fan master switch & a Thermostat, are they working correctly? Are you getting heat when you set the furnace temperature up? The fans will only work when the Thermostat is asking for heat.
Accessing the registers is fairly easy, each one is different, so lift the bed, pull the drawer out, remove the cabinet floor, etc. The fridge register return is in the front below the fridge, make sure all the returns are clean.
All are 12 v dc fans that can be cleaned or replaced. Check the 12-volt fuse panel in the Bedroom closet to see if it has a Fan circuit.
Hope that helps.
