blowing 5 amp fuse to heater & a/c blower on 2006 Mazda Tribute

have blown 4 fuses since august

Asked by for the 2006 Mazda Tribute
fuses blow for a reason and unless the reason is found, it will keep on blowing the fuses.
5 amp is a control circuit. it needs to be traced to see where the excessive draw is coming from. an electrical shop has the short finders needed to find the issue.
