Guys, can you help me solve this problem?

2020 Jeep Wrangler JL 2.0 with Halogen Headlights

Front:
  • High Beams, Low Beams, and Fog Lights are not working. ⛔
  • Only the High Beam Flash (Signal) works when pulling up the Lever on the steering wheel. ✅
  • Turn Signals work normally. ✅
  • Using JScan in Body Controller, I can activate all these front lamps manually. This means that the BCM and Headlights are connected to each other correctly. ✅

Rear:
  • Turn Signals, Brake Lights, and Reverse Lights are working properly. ✅

Interior:
  • Radio backlights and Climate Control Panel backlights are not working. ⛔
  • All other interior lights work normally. ✅

Update:

I have this type of Headlamp Switch - P68292842AC

JScan - Body Controller:
  • Headlamp Switch Position - Always OFF. ⛔
  • Headlamp Switch Voltage - The Voltage Changes when I turn the switch. (I don't know if these Voltages are correct) 🤔

Wiring Check:

I checked the wiring from the Headlamp Switch to the BCM with a multimeter. All pins are correctly connected to each other. ✅

Did you check that Fuse 46 is good and getting power?
Nevermind - that one must be good if you're able to get the lights to turn on with Jscan

Thanks, I'll check it today.
But in my case, PIN 9 is missing on the Headlamp Switch.
