12V power loss '05 Adventurer

'05 35' Winni Adventurer, Workhorse chassis.
Returned from a trip yesterday & all systems o.k.

Start her up today, went to open driver's power window & no go.
Ditto htr/ac, mirror control, rear camera, compass/temp. gauge, radio.
Instrument cluster o.k., ditto headlites, horn.

Checked fuse panel under dash, meter ck'd 2 - 30A fuses & seem o.k.

Has been suggested could be ignition conn/wire.

Any thoughts or suggestions?

Thanx, Bill

It does sound like most all of those circuits are energized by the ignition switch. There might be a relay the ignition switch triggers. Here's a link to Winnebago wiring diagrams:

Check the fuse that is used for the heater assist fan. I think that fuse is labeled "Rear Auto Htr" (on my Adventurer, it wasn't labeled). If that fuse goes a lot of 12vdc systems go along with it. The key to it I believe is the Backup monitor is not working in your case--it was same case with mine.
