2013 Tacoma 4WD light blinking and no beeping sound when changing

Hey guys I tried switching back and forth and driving forward and reverse and stopping putting in neutral then switching and driving again forwards and backward. The light stays blinking
And feels like I’m stuck in 2WD no matter what and there’s no beeping sound. Where should I start!?

Thanks guys

If you have a voltage meter and know how to use it.

I do and my bad i should’ve searched the threads for something like that. I’ll use this to post an update if that’s cool

 

sounds like you are trying to go straight to 4lo from 2hi?

You must get into 4hi first fully (solid light), then be under 3mph in neutral (auto) or clutch to the floor (manual) then click over to 4lo.

 

That will just fine.
Kind of makes it easier, that way we don’t get confused as to who we are helping.
