Welcome to the forum. To get the most/best responses, post in the Repairs & Maintenance section in a new thread. Also, go to the UserCP and click and go to Signature and create one with year, make and model as well as the same for your tow vehicle. Your questions will receive answers with more context.

You may want to pull each light in the bedroom area and check to see if the positive and negative 12V wires are touching on any. You definitely have a short where wires are touching or one of the wires going to the lights is touching metal or another wire lead, etc.

Thank you for the info. I’m not able to get to the wires where the lights are to check. It’s just a puzzle because they have always been working.

The advice George gave you was indeed correct. Pull the fixtures, one at a time, make sure the wiring attached is not a problem, reinstall and go to the next fixture.

Also, to help with trouble-shooting when you are going through a pile of blown fuses.... I keep a few of these in my TT in various amp ratings.

If you can remove the fixture, tug on the wiring. I have had stray brads and staples penetrate the wiring and over time with vibrations the wiring will short out.

What Chuck said. I'd leave the fuse out then remove the light fixture physically closest to the fuse panel. Place a VOM to ohms reading and remove the wires to the light. There most likely will be 2 sets of wires. One from the fuse panel to the light and one going to the next light.

With the wires disconnected take an ohm reading between the 2 wires in each pair. No reading or infinity, or "out of range" (depending on meter) will indicate no connection between the + and - wires. A zero reafing would indicate a direct short between the two wires. This will tell you the the direction to proceed. If there is no short in the wires then remove the light bulbs in the light fixture and test the light fixture. Operate the on/off switchnon the light fixture while testing. If it's the wire going to the next light fixture remove that fixture and repeate the process.
