tow/haul function

[kingsfisherman]

Hello all,

 

I have a 2003 Sierra 2500HD that the speedo stepper motor went out on
and now the tow/haul function has quit working. Any connection to the
stepper motor problem? Is there a fuse for the tow/haul switch?

 

thank you,

No connection between stepper motor and tow haul. Not sure on the fuse. More than likely the wiring to the tow haul button has broken. Remove the bottom cover on you steering column and check the wiring to the shifter.
