No light andin 4/wheel all the time fuses are ok

Worst case is that the TCM module is bad. It's located in the passenger side kick panel. It picks up moisture corrodes and the only fix is a new dealer part. $600!
I did avoid this once when the dealer found a small vacuum fitting that penetrates the firewall was cracked and leaking and preventing the actuator from working. that was a $10 fix.

Try this, go in reverse a bit and hit the brakes. Go forward and hit the brakes. Push the 2H button, or whatever the proper button is.a I swear sometimes this works.
