Blower motor fuse

[bigkiang]

Hello all, I'm going to try to explain this... I have a 95 Grand Cherokee that keeps blowing the "Blower Motor" maxi fuse when I try to start it. When I turn the key ahead a click or two everything happens normally, lights, radio, fuel pump, accessories, etc. When I try to start the engine... nothing! The starter does not fire and I get a blue flash from the maxi fuse... POP! I pulled the harness no visable broken wires. I disconnected the blower motor and put in a new maxi fuse and POP! Could my problem be a relay such as the starter relay? Is it somehow on the same grid as the blower motor? I am at a loss now. It all started when the battery went dead and the security system went down, I cycled the key in the lock to fix okay. The battery was jumped and ground on the negative battery post, could this have blown a relay which in turn blows my fuse??? Help! Thank you and I appreciate any assistance with this problem.
