HELP! 4HI light flashing

4HI light stuck flashing. When I start up the truck and it's in 4HI, I am able to switch between 4HI and 4LO. The problem however is I am unable to switch to 2WD. I checked all the fuses and they're good. I am a novice mechanic and need help

 

Does the light stop flashing or always flashes when in 4hi or 4lo

 

It flashes when its in 2WD/4HI/4LO. Constant

 

When the light flashed for me it was hung up between 4 hi and 4lo
Wheels have to be stright and drive under 45 to 4 hi
4 lo had to be put in neutral to engage was my experience if that didn't work check 4x4 actuator make sure you can hear it engage

 

Dumb question, but have you tried driving it forward and backward some? Sometimes throwing it in reverse will get it out of 4HI.

 

Front right wheel sensor code popped up. Nothing regarding 4WD unless that affects it?

 

That will defiantly cause the 4wd light to flash but usually accompanied by many other lights vsc, trac, etc

 

Yes VSC and trac are on as well

 

Change out that wss. I put a $25 one from Rockauto on my 07 about 6 years ago no problems

Do you have a link for the wiring harness that goes with it? Im a noobie and want to be sure its the right parts

 

The wire unplugs from the sensor I didn’t replace any wire
