Fleetwood dash A/C evaporator access

I have 2001 Bounder model 39z diesel pusher. Dash does not need to be removed.lower half of ductwork that houses evaporator comes out. The leak was actually the pressure switch next to evaporator.. Mechanic removed evaporator housing in 20 min. Pictures available if needed.

I was wondering the same thing for a Winnebago Adventurer, 2003.

On my 05 Fleetwood Expedition, you take the defroster vents off, take out the screws hiding under button covers then the entire dash top comes off. We had to replace the thermostat in the evaporater a few years back. Denso has schematics and wiring diagrams on their website. Fleetwood sent me mine.
