I finally found a forum that helped me fixed my ac not blowing hot air issue. I thought at first my compressor went out, the relay was burned from under the hood and I replaced that with no success, I even used the horn relay with no success. I tested the wiring and looked at every freakin thing. I too did not find the interior fuse box behind the coin box. It was there but way the f**k under the dashboard as the previous comment mentioned. I finally found the #24 fuse 10 Amp was burned up. I replaced it and that wonderful cold air came out once again. I almost took this car to a mechanic and I knew it would cost a pretty penny. Hope this helps the next fellow.
