Tow/Haul switch not working
My Tow/Haul switch does nothing. No light on the dash, does not shift out of OD. I've looked at the fuses and relays and can't see anything suspect. No codes. I have SCII and Torque Pro app with bluetooth adapter. Can I find out anything with these?

When tow/haul is working it won't take it out of overdrive. That's not it's function. It changes the shift schedule.
The most common cause of this problem is the wires wear through where they enter the shift handle. You can take the cover off the cold and either fix the wires or replace the shift handle.

Replaced mine when I first bought my 03, the truck was possessed and would go into tow haul on its own. Wires were broke and I figured that is why the first owner dumped the truck. Only had 9k on the clock when I bought it.
