Air Conditioning problem 6 cyl Automatic

Hi, my '97 Monte Carlo LS recently stopped blowing cold air when the A/C is turned on. I have a can of Freon (or whatever you call it) with a gauge that I can put in to recharge the AC. My question is, where is the opening/plug for this? I need an image and/or a very detailed description of the location, because I can't find it ANYWHERE! I remember when my car had been fixed before, they took something off in order to get to it.

Any help would be GREATLY appreciated, because I need AC!
