i bought my blazer a couple months ago and i noticed that somebody had put a switch in because when you turn the switch for the fan to come on it didnt so somebody just ran power to it with there own switch. now there is no fuse in the fuse box for the heater\ac slot, and when i put a fuse in it then turn the key on it blows the fuse automaticlly. i tried to disconnect the switch then put the fuse in but it still blew the fuse. i have no idea where to start looking for a short hopefully you guys can point me in the right direction. thank you
