Headlight issues with my 2022 Thor Freedom Traveler a32! Low beams work fine.
When I switch to the high beam both right and left high beams come on then the left high beam goes out and only the right high beam stays on.
Along with this issue is the front left side marker light (orange) which is off when the low beam lights are on but comes on when I switch to the high beam which only the right high beam stays on.
Any ideas. jb-2025
 
Hello 16ACE27, thank you for your interest and reply. So, are you saying that each light has its own ground wire, and I need to clean and reconnect? Or is the issue with the bulb not making contact with the ground when inserted in headlight receptacle?

You asked for ideas as to the problem. A bad ground connection is my idea. Where it is will take some troubleshooting with a multimeter and maybe a ground jumper wire. Bad grounds are a known Thor issue. That's about as good as it gets for electrical troubleshooting over the interwebs.
 
Whenever automobile lights are acting weird my first thought is a poor ground. That can cause a lot of odd behavior. Some lights have a dedicated ground wire, some (try to) get a ground through their mounting screws. We don't know exactly how your RV's lights are wired so some detective work will be required. You may find as you touch & jiggle things the lights suddenly work or stop working. That's a big clue that you are close to the problem.
 
If you're comfortable using a voltmeter, determine terminal polarity at a problem light. Then short the negative terminal to ground. If it illuminates... there's your dinner.
