Lost power to mirrors, mirror warmers, and cameras, where's the fuse?

Where are these items powered from and where is the fuse(s)?
2012 Greyhawk 31FS, Clarion Radio.

Does the Clarion radio still work? The fuse for the radio is behind the house battery. There is another fuse next to it, but I haven't determined what it is for.

The radio and GPS still work. It has to be a circuit for the mirrors, de-froster and cameras, causing the outage.
Guess that is what I get for using the defrosters.

I dont miss the side view camera, but I need that back up camera...

Have you called Jayco? They were spot-on when I lost power to my radio, and I would have never looked behind the battery on my own.

Yeah, I sent them an email about the same time I posted this. Vinh is good about responding once he gets the email routed to him.

I did not want to be presumptuous with so many technically savvy members out there, but last winter I tried to inflate my tires with a 12 volt pump. It blew the fuse and I had no 12 volt or usb power until I had the fuse replaced under the hood. I would think that the defroster is part of the chassis and would also be in the fuse box for the Ford rather than the coach.

I searched for the culprit fuse and found it. Their are two fuses behind the battery tray. They were good. There are two fuses by the quickee Step frame, they were good. All fuses in the breaker panel were OK. All under hood fuses were good as well. Popped the panel off under the steering column to find a big rats nest of wires. There I found two Jayco added fuses, one in a red fuse holder with cap. This 5A fuse was the blown one.

After replacing it, mirrors, mirror heaters, cameras and quikee step over-ride ignition circuit all work fine!

I can only imagine how much money a corrupt evil minded service center would charge to diagnose and replace a fuse. I bet they have made thousands on stuff like this.

Here is a pic of the dash wiring. The module is for the cameras and all wiring that goes to the house side from the clarion radio passes through this spot. You can also see all the A/V wire sets.

Thanks for this post. My side and rear cameras went out on first road trip. Mine is a 2021. Guess they are still having issues with that system.

Wow! I was pulling my hair out! We'll not really... Thanks to this site I was able to find the fuse and of course it was bad. Thanks so much..
