1997 GMC Sierra V8 Four Wheel Drive Automatic 155000 miles

I was driving my truck in four wheel drive yesterday due to icy conditions, and while I was driving the four wheel drive quit working. When I press the button to engage the four wheel drive it just blinks and never engages. It does this when I try to engage 4hi and 4lo. It never made any kind of sound when it quit working. Hope you can help! Thanks, Nick

Probably the 4 wheel drive electronic switch. I had to replace mine in a similar way.
