I have a 1996 Chevy Lumina APV. The A/C worked great for a recent long trip but then on a shorter trip all of a sudden the fuse blew and all of the instrument panel went out. We replaced the fuse and almost instantly (with the blower turned on) the fuse blew again. We tried a new fan, still blows the fuse, a new relay switch, still blows the fuse. Does anybody have any ideas of what to try next? We are heading on another trip and it will be sweltering without that A/C working. Thanks in advance!!!!
