No 4wd no dash indicator lights

What is your question?

Truck wont go into 4wd none of the indicator lights are on. Dont hear any motor or noise when 4wd high or 4wd low button is pushed. Last year I had a hard time getting it out of 4-hi. Dont know if it's related. Dont use 4wd often.

What makes this problem better or worse?

Its worst when your stuck in the snow and it won't go into 4wd. Really never a problem in July on the highway.

How long has your 1996 GMC C1500 had this problem?
