the four wheel drive indicator switch switches almost everytime I start the truck. when I try to switch it using the buttons nothing happens. It seems like the truck has a mind of its own at times and will change in to four wheel drive low and it makes it hard to accelerate.

push button engagemaent of 4x4 and 4x2 somrtimes will not engae at all. Usually transmission will default to computer controlled four wheel drive. After vehicle sits for a few hours push button control returns.

I bought a 2006 Silverado that has a service 4 wheel drive light that comes on when driving for a short time. I notice that a visitor posted that he bought the switch to resolve the problem for 35.00 online and replaced it himself. If I can the info. from the place the switch was purchased will be helpful. Thank you.

While idleing truck will put itself into 4 low, I put truck into neutral and gassed it then tried to push buttons to put back to 2 wheel. Put it into gear and gassed hard and could hear it click back. Keep wanting to put itself into 4 low though

The switch changes its self at times and I have to stop and shut down the engine for a few minites for it to shift back into 2wd, the switch itself does not seem to work.
