In the GM underhood relay/fuse panel in general, there are also some small fuses, one of which relates to this problem. Pull some the smaller ones, like a red 10 watter, starting near the pump relay, and check the element. Also, it may be the fuse that blows if there is a problem (short circuit) where the plug goes into the AC compressor. If you find the blown fuse, and it blows again, check connection to AC compressor.
