I recently installed a new radio in my truck and had to take apart the dash to get to the radio. I unplugged everything including the electronic 4 wheel drive button and fan for the ac and all the other stuff located in that area. Well when I put everything back together and started my truck up I noticed that on my electronic transfer case switch the N was lit up but my truck was in two wheel drive and was still moving? The switch will not work either, the truck will not go into 4 hi or 4 low now. Please help!:{
