High beams not working

Hello, I'm Danny.

The first thing I would check is the high beam relay. Here is a tutorial showing how to test relays:

The high beam relay is located in the under hood fuse box in location # 34. I've attached a picture below and circled in red. Hope this helps and thanks for using 2CarPros.

Hello again.

If all the fuses, relays, and new multi-function switch are in working order then it sounds like you have a wiring issue. Here is a tutorial on how to test wiring:

I've attached a picture wiring diagram below of your exterior lighting system for your car. I've cut the picture into 3 pieces so you can view larger. I would first check the ground that I've circled in red as a start .Check to see if the connection is not damaged, loose, corroded, or otherwise faulty. Let us know what you find and we'll go from there. Hope this helps and thanks again for using 2CarPros.
