The service 4wd light comes on intermittently and when it does can not shift out of 2wd. Is this a vacuum switch or encoder problem? Where do I begin

What I recommend is having the computer scanned to determine where the problem is coming from. It could be an electrical or vacuum problem. Most parts stores will scan for free.

Let me know what you find.
