Reply to "AC Not Blowing Cold"

Checked the AC fuse with volt meter and test light and it has juice, plus I tried the horn to wake the neighbors and the horn works too (which mentioned above, operates from that fuse too). Also, was able to shut it down and keep the key on so that I don't hear the loud FI system, and I turned on and off the AC knob but did not hear any click in the engine bay. I tried the same technique on my group 4 just to see if I would hear anything back there, and when doing it in that car I could definately hear a loud click in the engine bay when truning the AC switch. So, maybe the relay to check next by replacing it? I suppose when I open that relay/wire box I will see all kinds of relays, so maybe just guess which one? I decided to check all the fuses on the fuse panel too, and not all of them light up with the test light (not sure if they are supposed to or not, or maybe just when using that item for the fuse). Did not want to get into the bulkhead if I don't need to for a visual. I don't think it is the refergerant because I had such cold air just a couple weeks ago, and now suddently just warm air.
