Right Turn Signal turns on High Beams???

[stimpster]

Hi. Sorry if this has been asked, I couldn't find it.

On my 2008 Yukon XL with 240k miles, when I use the right turn signal the high beams come on.
How do I fix it? Do I replace the stalk?

My 18yo boy is driving this now, so I need to fix it ASAP.

Thank you very much for your help!

Stalk certainly sounds likely, haven't heard of that issue before!

Does anybody have any other thoughts?

How hard is it to install the whole stalk, if still available?

Thanks!

Don't know how hard, but I bet it's not too bad...

This is the part that shows up on rockauto for 08 yukon xl 1500 5.3

That would be a first for what you described.

Thanks for mentioning your kid driving it. By chance has he added any aftermarket LED light assemblies or bulbs to the truck?

What you described is how these trucks can respond to the diagnostics interpreting a voltage similar to the 5v canbus diagnostic system.
