Im having a problem with my hvac. The problem is it keeps blowing fuses, which i know the problem is prob a short but where? Its not the fan its in the selector. I can keep it on one setting say floor and it will be fine for sometimes a couple days and had been for a month, but as soon as I would try to turn it to something else. pop! ANyone have any idea where I would even start to look?

 

would that work? Do you think the problem would be in there?
