All the vent hoses are coming off the box that contains the fan, heater core, and evaporator.
No, I can't see any 12V wire from inside the coach to the compartment behind the plywood panel. There's a bunch of wire in general behind the glove box. Without seeing the blower motor, I wouldn't know how to isolate them.
On my pic of the box in the hood area, there are two heater hose lines hooked up to what is probably the heater core and behind that there is some 12V wiring and what I think may be the blower motor, but without removing the heater core, there's only about 1" of clearance to see anything.
I've had another person go inside the coach and try to poke a screwdriver through to the box in the hood area, but I can't see it from the outside. I'm just not sure where to go next.
I might end up buying one of those snaking camera systems and try to find the blower motor with it before pulling anything else off.
