Electrical Issue-Fuse Relay

[Jabber Jaw]

Hopefully this will help if you have this problem.
Started as an inoperative driver's power window.
Well, later no rear camera, dash "hvac" controls, nor radio, and no power mirrors, nor heaters, nor fog lights.
And no blown fuses! What a problem!
Now, a solution!
Fuse box on firewall under dash.
Has 4 RELAYS!
One RELAY, top right, controls all of the above mentioned items.
Replaced that RELAY, and everything is operational again, including the power window!
Summary, check RELAYS, as well as fuses!
A $5.68 RELAY, necessitated a $300 plus RV tech to find the issue!
Hope this may help you in the future!👍
PS: 2020 Canyon Star "3710"

A pic of the relays would be helpful.

Good to know. Might save someone else $300 or more having a tech find it.
