A/C FUSE

2004 Toyota Corolla • 140,000 miles

I noticed the A/C wasn't cold anymore and the little green light on the button was off and it wouldn't turn back on. I troubleshot it and found out it was the little 10amp fuse was blown. I replaced the 10amp fuse under the driver side dash but the fuse only lasted about 12 hours to a day and then it blows. This happened twice with a 10amp and then I tried a 15 amp. Still only lasted a day and then blew.

No, no, no. You don't use a bigger fuse. That's how you destroy expensive components and start fires. You have to find out what is overloading that circuit. If you don't have extensive electrical circuit understanding, this probably should go to an electrical shop. They will know what to look for and where.
