Can anyone help, Heater fuse #24 keeps blowing.

(1997 Lexus ES300)
in Tampa, FL on April 23, 2012
I have 97 es300 Lexus and the other day my a/c control lost all power. After investigation I found that the fuse under the steering wheel marked heater 10 amp was blown. I replaced it and got power, for about 5 seconds before it blew agian. So I tried another, and another the same thing. I tried putting a 30 amp fuse to see what would happen, so now the power stays and it's blowing air but my a/c light is flashing and no cold air. I think maybe there's a short but not sure. Has this happened to anyone, or does anyone have suggestion's?

never put a larger fuse in place of a smaller fuse, the system is trying to tell you there is a problem. you may cause further damage with that fuse. the a/c is flashing a code,but you should seek help for this repair.
