If this question is not allowed...please delete. I picked up a 99 1500 Z71 winter beater to save some miles on the 08 DMax. Everything works great on the beater except the tow haul doesn`t work, nor does the dash indicator light come on. I can`t seem to locate the problem. Is there someplace I should look first?? Thanks!!

Post what you find. When I got my 99 gmc back from my nephew, the tow/haul button doesnt activate, nor does the light come on. Since the remote start doesnt work either, I figured he messed with the wiring in the dash for some reason. He denies everything that is wrong with the truck as he just woke up and this n that started going out.... 
Thank you very much for the tip....that was the problem. Wires were broken where they go thru one of the looms. Now the tow haul works fine...and the indicator light comes on too
