Okay so I have a 2013 Nissan Versa in which the a/c is out. I first tried to replace the fuses. They blew immediately. So I just replaced the resistor. And replaced the fuses to try it out again. They immediately blew. Again. So what else could it be? I plan to replace the blower motor. But what electrical problem might I look into next? Or even small problem that could be an easy fix? I noticed it releases hot air sometimes. Not always.
