Under the hood on the pass. side is a fuse box and on top of that fuse box it reads various systems, Air conditionng being one of them. I hadn't used the a/c since before my alternator got replaced and Saturday I used it for the 1st time since, and when I got under the hood Sunday to check my oil, I saw that the fuse box had melted right on top of the portion of the fuse box that says "air cond". Why the hek did it melt? Do I have a short? The a/c worked fine BTW Used it for for approx. 30 minutes. Has this ever happened to anyone else?
