1997 Chevy Blazer A/C Doesn't Always Blow

When I start up my Blazer and turn on the A/C, it almost always start working right away. Recently when i start up the vehicle, the A/C compresser turns on like normal, but no air will blow. I'll Drive about a half a block down the street, more or less, Then the blower kicks on and everthing is fine again, for a while that is. Usually i keep everything in the on position when i turn off the car, so when i use my Remote start its already blowing cool air. Also there are two main A/C settings on the blazer. A/C MAX and A/C. Should the air stop blowing, On A/C MAX there is no wind at all, but if i have it on A/C, it doesn't start blowing regularly but you can feel it blow minutely.
