2014 Lexus ES 350 buzzing

There is a buzzing noise under the dash ( under steering wheel area, and to the left of it). it is intermittent, but getting more frequent. it’s very annoying and the dealership can’t figure it out. They say it’s " nothing"!!!

Could be a turn signal flasher unit, or emergency lights flasher. Another idea, climate control system door actuator. Try monkeying around with the AC/heater controls, turn signals, and emergency flashers button, see if they have any relationship to the noise.

The Lexus dealership here can’t figure it out. They say it’s nothing .

Do you have any suggestions for a good mechanic ?

Thanks for your input.

Best method imo is a personal recommendation. Ask your friends, family, co-workers, fellow church-goers, etc which shop they use. From there, choose one that specializes in Toyota/Lexus or at least Asian cars. And be sure to tell the shop you choose who it was that recommended you. Gives you a little leverage.
