I have a '97 Chevy Blazer, 167k miles, auto trans, 4.3L engine, 4wd. Just changed the alternator, now no air blows out of the vents, seems to be stuck in defrost/floor mode. Last time this happened, it was the vacuum accumulator. Chiltons doesn't show how to check if that's the problem. Any advice?
