A/C Problem- Only blows on low and medium
 

Hi Guys,

I am new here. Found this site while trying to figure out where to start with my A/C. It only blows on low or medium. When I turn it to high everything shuts off. If it only blew on high and not low and medium I would suspect the resistor. I am thinking it is either the switch or the module(?) behind the switch. Anyone seen this before?
