Some time ago my tow/haul light stopped coming on when I hit the button. I figured it was just a burned out bulb since the mode seems to work as it always had. However, I put the dash in test mode the other day (holding the odo button while turning the key) and to my surprise the Tow/Haul light lit up!
What could be causing it not to light up when I'm using the mode? Is this an indication of something wrong with the tow/haul function?
