As far as the 4wd thing goes, this is normal operation when on dry pavement. You are actually causing the transfer case to bind. This happens when the steering is hard over.

While the switches on the control panel can fail more commonly the vacuum lines, check valve or vacuum reservoir will fail first. Locate the vacuum source line and measure engine ...

The check valve is that little black and ...
with the car running, use an aerosol can of carb cleaner with the straw in it to spray around the vacuum lines and fittings. When you get to the leak point you will hear the rpm change. move slowly and use spurts.
