Electric diagram

[zb39]

Anyone know where I can get an electrical schematic for a 2019 Berkshire XLT 45B. I lost power to my heater fan in the dash, the 2 fans up high on the windshield, the USB port in the dash, and my power mirrors. Also lost power to the AC switch in the dash.
I checked every fuse I could and they are good. I'm wondering if I lost a relay or fusable link to power the dash.
Any help appreciated. I called frieghtliner and they said all that is installed by forest river .

There is a continuous duty relay in the first bin on the drivers side that might be stuck. There are 4 studs. Tap it with a screwdriver handle and see if that fixes.

Sounds like the solenoid in the front run bay under the driver window has failed or has an intermittent failure. Like stated above you can tap on it to see if "wakes up" but it will need replaced. When you replace you will need a 12V continuous duty type not a starting solenoid. Attached is a pic of the solenoid.

Does the solenoid wake up when the key is on? Everything else works great.

I just drove 2K miles back from out west.

I will check on this when I get home today.

Yes that is the ignition solenoid. So when the key is on those components are powered Dash fans, NAV/Stereo, Dash AC/heat etc have power from that solenoid.

Thank you Shepardmike and Lincman983 for your answers. You both were spot on. I tested it tonight and nothing with the key on. Only hot on one side even though the left small black wire was hot. I jumped the solenoid across and everything came on.
I will get one ordered. Thanks so much !!
