When I turn my right turn blinker on the high beams come on, I'm not sure if that is a warning of another light being out or not? Could it be that the switch in the steering wheel column is gone or shot?

Might you have any idea what it could be? Any suggestions or help would be very grateful as always.

This must be a wiring issue because the blinkers do not intersect with headlights in the wiring diagrams. I would start at the front right headlight and blinker wiring to look for damage or wiring repairs that were not done correctly. Here is the headlight wiring so you can see what's going on.

Please go over this video as well:

I have never seen in my 45 years of working on vehicles where you flip on the blinker and the high beam comes on. That's a great place to start. I thank you very much for that and as soon as I get time I'll start looking. Again, you guys the 2CarPros are so awesome absolutely the best and I recommend all my friends to contact you when they have issues. Thank you again so very much and I hope you guys have a wonderful day.

Hello Ken, well I attached a video to show you what is going on. I checked the headlights and the blinkers and there doesn't seem to be a short anywhere in there that I can find. So maybe with the video this will help out.

Perfect, thanks for the video, it looks like the shared connection is in the multi-function switch, here is how to change it out which should fix the problem. Check out the images (below). Please let us know what happens.
