Hi Ken and thank you for your answer.
I check both fuse as indicate , they are good and nothing change.
Note that radio and mileage display shuts off only when i switch on low beam.( first position) on high beam (second position) they light correctly.

I would recheck the wiring to the headlight switch and then replace the switch. Please let us know what happens.

yes, but i do not know how to test the wire. so many.
