96 k1500 2WD light Intermittent
 

I have a 96 Suburban 4wd 1500. The 2wd light will drop out once and a while as your going down the road. I here more noise than normal from the front end when this happens. It doesn't seem to be in 2 or 4, but somewhere in between? I push the switch and it takes a minute to engage again and its seems ok, the front end quiets down. Any comments on this issue?:confused:
