I have a 2005 Dodge Ram 1500 and i went to put my truck in 4x4 and the light on the dash did not light up yet it was in four wheel drive. i also did what i beleive is a check for all the lights and guages where u hold down the tac needle and turn the key to on and all the lights and guages light up the 4x4 and serv 4 wheel drive lights did not light. My question to you guys are is do certain instrument pannel lights run on a fuse or something or if i want those lights to work i have to buy a new instrument pannel
