4x4 problems

I have a 2000 chevy blazer and I am having problems with the 4wheel dr.
when I start the truck everything is good with 4x4 but half way through the trip service 4x4 light comes on and 4wheel dr stops working any ideas on what could be the problem. getting very frustrated.




tried reseting but dosnt fix problem think it might be a switch or something
