    A/C fuse keeps blowing

    Hi,

    I popped the hood the other day and realized that the a/c fuse in the engine bay was blown. i replaced the fuse with a new one and it worked fine for about 10 minutes then it blew again. My fuse cover does not have a sticker, is 20amp the proper rating? Also what could cause the fuse to go? Everything seems fine until the fuse goes...

    Thanks.

    A short somewhere in that circuit, including a component itself, would cause that kind of problem. Those are the worst kinds of problems to diagnose. If I can only remember to check for you to see if the fuse rating is too low. However, it didn't blow before with that fuse rating so there's probably something wrong like a short.
