Good day, I have a 2002 Envoy SLE, this is the first in this line of SUV's that I have owned and thought it strange that I have not seen any other comments about this issue. When I turn on my key to the run position, none of the gauges, lights or accessories work as I have noticed in all other vehicles I have owned. nothing actually works until you start the truck then everything functions as it should. The windows don't even work with just the key on.... Is this a normal thing for these vehicles or is something actually wrong with my unit?
