Few electrical problems on 2001 GMC Sierra
I have a 2001 GMC Sierra 1500HD with the 5.3 in it.
The first problem.
My tow/haul mode button on the shifter handle doesn't work. No light comes on, and the truck doesn't shift down, or rev higher between gears. Where is a good place to start trouble shooting?
And another problem. The dash lights in my headlight switch, and in my heater switch control don't work. Good place to start trouble shooting that?
Thanks
