97 sportsmen 4x4 gone bad?

[Mudcat21]

Wondering if anyone would have an idea on what could be the issue with my wheeler. I push the "AWD" button and the 4x4 doesn't kick in. It started this past winter, for a while only three wheels were turning, then this spring nothing in the front works anymore. I can drive it just fine just the 4x4 is not working. Like everyone else out there....money is tight and wondering if this is something I can tackle myself or is it going to make a trip to the shop. Thanks for the help!

1997 should have the push type switch for the 4x4 (not the sliding switch like the newer models) A quick thing to check is the little bulb in the back of the switch. The 4x4 will not work if the bulb is burned out.

also try draining the hub fluid and refilling with some new stuff.

Armatures come to mind with what rundrave said. If you do the hub fluid, you might also want to look at the armatures. They might be in need of a resurface job.
