Now...sometimes I dont recommend this...but I had a OLD chevy fan ...kept blowing the dash light fuse, I spent many days ,hours,an I even let another tech or 2 try an fix it,,, nothing, So It calls for a 7.5 amp fuse, I stuck a 30 amp fuse in an wait about few secs then you will see smoke, I followed the smoke an warm wire, an come to find out , the cluster was bad...lol....but this is a REDNECK trick lol...
