Any input guys on why my tow haul is not working no light and no tranny response? Does this run off a solenoid? Maybe a fuse any help is appreciated.

 

I believe it is just a signal to the computer to toggle in and out of tow haul. Guessing the switch is bad or the wire coming off the switch. I haven't had the steering column off but it could be a chaffing wire in there somewhere. Good Luck.
