Last week I took off my plow when it was warm up here in NY and 4 wheel drive was working fine. Today snow is flying and I hook up the blade and cant engage 4 wheel drive, not in high not in low. Kinda rough limping around pushing snow up hill in 2 wheel drive. A friend told me it might be the on demand switch, anyone with experience in this help me? Please?

Youwill have to go under the truck where the solonoid is and check to see if you are getting power to it to see if it is working or not. But check your fuses and relays first. Check the switch as well, before crawling under the vehilcle.
