I have a 97 K1500 5.7L that I inherited. Finally got around to charging the a/c. After charging, I started it up and ran the compressor (a/c on) and after about 6 minutes, the 30 amp AUX B **** fuse popped and truck shut off. Replaced fuse and restarted the truck. Paying close attention to the fuse now, while compressor is running, the fuse gets so hot you can barely keep a finger on it. Compressor off, fuse cools down. Eventually after a few minutes, the fuse popped again. Why is a fuse meant for accessories popping when the compressor is running? Is this a ground issue? Can compressor drawing too much current cause this?
