When I put my blower together and got it tuned, a few days later the 50amp fan fuse blew. I traced the problem, replaced the 50 amp fuse and it has been good for over 2 months. The last week my a/c has been blowing non cold air occasionally, and today I was sitting on the highway in traffic and the temp gauge went to about 235-240. I shut it down and let it cool, checked the fuse and sure enough it was blown. I replaced the fuse, fired it up, the fan tried to spin and blew the fuse again. I honestly don't know where to start, I've done a lot of searching but haven't found really what I'm looking for. Suggestions would be awesome, thanks!
