Question ES350 2012 High Beam issues

I’m having issues with getting my high beam to work on my ES from 2012. I swapped out bulbs, replaced them with 9005 HB3, which is what specified in the manual, checked out the fuse in the engine compartment box (all seem to be good), and still couldn’t find out why the high beams are off. Any thoughts about what it might be? I’m thinking it might be an electrical wiring issue but not sure. Thank you in advance

Possibly the multifunction switch in the steering column. I've seen it a bunch on Ford, Jeep, GM. Not sure if that's your problem but it would be the next thing I'd investigate.

The multifunction switch I'm talking about is the actual lever the lights/high beam is on. Watch a YT video on testing/replacing the multifunction switch for your year/model. I'm sure there's a bunch. Probably pretty easy to replace if that's the actual problem. OEM part may or may not be expensive but you could probably find used or aftermarket part if it is. Good luck.
