hmm, i dont know about your blazer but this happened to a friend of mine and his alternator had gone out maybe 2-3 weeks after he first noticed no heat just cold air. I would go have your alternator tested, that may be the cause.

No heat = bad heater core which probably means the antifreeze blew out all over and the car could be overheating also. If it's not that is could be something I don't know about.

Have the cooling system pressure tested if there are no leaks then have your heater core back flushed.
