    Not a blazer But I have a 95 s10 that has push button 4 wheel drive when driving it, it kicks in and out of 4 wheel drive on its own. Anyone have any ideas what is causing this?

    More than likely the vacuum modulator on the front axle that activates the 4WD system. They make a mechinical actuated replacement for this (cable and t-handle).

    Right on muddin! Buttons are for radios and remote controls...NOT transfer cases.

    Like wheels said, the frontend is activated by vacuum, check the lines and fittings for leaks and or kinks that would impede the flow. All else fails, pull the unit and have a friend activate it and see if it moves correctly. You may just have a turd blocking the actuator... Good luck.

    Why do people keep calling it a Bronco!!!!! [​IMG]
