Resolved Headlight Issue

I have a 2015 Newmar DutchStar 4369. My headlight on the passenger side won’t work. I have changed the bulb and checked the fuse. It works when I have them on bright as it is a 4 headlight system. But on dim it won’t work. I guess my next target is to check the steering wheel control module. Does anyone know where that is or what it looks like? Looking for help. Newmar can’t help. They say it is a Freightliner issue and Freightliner want $260 p/hour to wrk on it.

@Freightrain I had the exact problem with our 2014 DSDP. I had Freightliner in Gaffney change the bulb. Neither they nor I checked to see if the problem was resolved, It was not. Took coach to a Freightliner Service Center. They indicated there was an electrical short in the harness. They tried to find it but simply performed a wiring overlay from the driver's low beam. Still did not work properly.
Rarely do I drive at night. On a day trip I had to use the windshield wipers which turn on the headlights. Once back into my storage area I sensed a burning smell. I looked around and found that a wiring harness/relay located in the electrical bay under driver's seat had melted.
Took coach to Independence RV in Winter Garden, FL (Now General RV). They replaced the wiring harness and found upon testing the new harness was getting very hot. They reached out to Newmar who indicated a new diode pack was available. The diode pack was installed and the heat dissipated.
There was another DSDP on the lot at the time of my repair. They checked their headlight harness and found it was getting too hot. They replaced the harness and install the diode pack on that coach as well.
I wonder how many coaches are out there with this problem and may not know.
There was a recall about 10 years ago tied to this headlight harness.
Best wishes!

Thanks Just FYI, I broke down and took mine to Freightliner this morning. They found diode pack was the issue. They have ordered me one. Should be here tomorrow. But thanks for the info and reply
