Faulty Dash Fan...
I shared in the intro section a quick brief on a dash fan issue in our 2019 Aria 4000 with the fuse blowing when the fans run on HIGH.
Saturday I found the culprit: apparently the right-side fan is faulty as I had them running on LOW and after 10 minutes or so the right side fan slowed to a crawl then stopped completely! The left fan was still running so I felt the motor-rather warm but no cause for alarm. The right fan however, was cooking in place-too hot to touch with a bare hand and the smell of burning wiring (perhaps from the armature) was noticeable!
Thankfully I was in the coach when this thing cooked off-another fix-it for the dealer....
