Rusted or cracked vacuum lines, bad relay, hubs need serviced, any number of things.

I just read on the other forum for the pickups and they said to check for vacuum leak if your ac switches from your dash to your defrost when you turn on your four wheel drive you have a vacuum leak and mine is doing that. So hopefully a simple hose problems
