Maybe an issue with nultifunction switch/dimmer? In the diagram the gray wire is voltage for high and low beam, comes from the light module. Any applicable trouble codes?

Usually that isn't correct. If you have an inactive code, it would still be there, unless the code was manually erased or a certain number of drive cycles was completed. I'd have to double check that on your year--make and model.

I gave you a diagram.

Check headlight relay in the fuse panel under the hood. Your owners manual should tell you which one it is. When you pull back on the flasher it runs through a different relay. The headlight relay is a common item and most automotive stores have them

No problem, I will check on it. There might be a diagram of the relays on the inside top of the fuse panel under the hood of the car on the drivers side
