Hi all, looking for a little help with my truck. When I bought it last year the 4wd wasn’t working. I assumed it was the switch since the **** would pop off. So I found one online and replaced it- no change. Today I installed a new transfer case shift motor- still no change. When I switch the dash switch from 2wd to either 4lock or 4lo, nothing happens at all. No noise on the shift motor, no dash lights at all, nothing. All the fuses in the box look good. Any advice? Really want to get this 4wd working. Thanks!

 

Bad controller??

 

Sorry not sure what you mean by controller

 

Transfer case control module. On some, it's a separate little box, not sure about that on yours.

 

Initially I thought it was, but I figured out on mine that it’s supposedly built in to the shift motor because they stopped using the TCCM in 05. But honestly I’m not 100% sure. Any idea where I’d find the TCCM to see if it could be a problem if I have one?

 

OK, apparently, in 06, there was no separate module, it is integrated into the TIPM........ See if there are any fuses for it in there.
