I don't know much, I bought the truck from my brother and he told me the 3 button 4x4 switch just needed to be replace, so we replaced it, but it still doesn't work. Occasionally, especially in hot weather or really cold weather, the transmission sounds and feels like the 4x4 is engaged. When the key is first turned the 3 lights on the switch will light up for maybe 2 seconds, but other than that the switch is currently just a decoration on the dash. I am having other electrical problems with the truck. The dash board is also glitchy, the oil pressure, temperature, voltage meter and speedometer work, but nothing else does. And occasionally all the lights, like the airbag, seatbelt, etc. will stay on.

ok

the problem with the 4wd sounds to be the acuator on the side of the transfer case,,these cost around $150 at your local parts store...the dash light problem may be the ckuster itself,these tend to go bad
