Re: 4wd light stays on when the truck is in 2wd

Update:

I replaced the part that the manual refers to as the Wait Detection Switch. That other name for that part is SWITCH ASSY-NEUTRAL,TRANSFER. That however did not resolve the problem.

I went through the test procedure again, and this time it was pointing to the 4LO switch. I decided to replace the ATP switch as well if I was placing another order. Although the ATP switch was replaced by the dealer under warranty at 76k miles (truck is now at 91k), I figued it was $18.

Anyway, I replaced both of the switches, and afterwards, I didn't see a single 4wd light. So far I've only put ~35 miles on the truck since replacing them, but so far it seems good. I will update this thread after some time goes by just to be sure that the problem went away.
