Never seen these 4wd buttons before...

Considering replacing my Tahoe vs fixing it up. Saw a good deal on one but noticed this....I'm confused.

Looks like an aftermarket replacement switch:

That's an awd Tahoe. It always in 4hi and has selectable 4lo. The other buttons have something to do with stabilitrak I think.

It's awd...... the top button is for traction control, the middle button is to turn on awd (if in 4low) , and the bottom button is to turn on 4low (if in awd). My suburban has the same system.

Over time, front differential in AWD GM vehicles can have problems due to power to the front diff continuously.
