Just bought a Blazer LT with the Automatic Transfer Case (has the Auto 4WD feature). The car drives fine in 2HI, but when I try to shift to Auto 4WD or 4HI, the lights on the selected button blink for several minutes (as the manual says they should when shifting), and then it stops and the 2HI lights comes back on. Does anyone have a fix, quick or otherwise, for this problem?

try this, the four wheel drive module is located in the passenger side kick panel "from what i can remember" disconnect it for 30 seconds and reconnect it. try to engauge your 4 wheel drive and see if it works. if it does you need a module.
