Why does my air stop blowing when I accelerate?

Does defrost work without AC?

I actually find that putting the heat on the defroster vent with no AC works the best. Sometimes even with the AC it doesn’t clear fast enough or well enough. I keep the heater on it with no AC on (some cars you can defeat the AC on with defroster, did that to my Civic), works great.
