hey guys i just realized my tow haul mode doesnt work i press the button and nothing happens no light on the dash comes on or anything. any ideas? i can still use the manual mode and shift on the shifter but no tow haul
 
The button itself has been known to go bad but I'm not 100% positive that is it. Be my guess though.
 
I was thinking you could just replace the button, but not sure.
