I was driving then all the sudden it started blowing hot air. Found the the fuse was blown. Replaced fuse, blown again. I've tried five times and it blows it everytime. Tried a 20 fuse did not blow but the A/C light is flashing no cool air. Why is it flashing and why does it keep blowing the fuses?

 

Were it my car, I wouldn't put in a fuse that is larger than what is called for. If I'm not mistaken, when your A/C light flashes, there is a problem with the A/C mechanically, I'd get it checked out by a tech.

 

blown fuses means a hot is touching a ground some where.... which means that you need to kix it not replace it with another fuse and deff not a larger fuse. A fuse is a safety percaution... thats like running over a nail and instead of patching it just filling it back up with more air so it lasts longer.... very bad.
