2004 Pathfinder ac blower motor won't work
 

Hello. My ac blower motor will not work on my 2004, V6, 3.5 pathfinder and I cannot figure out exactly why or how to fix it. I replaced the motor because the fan stopped blowing but it still will not work. I have read many other posts talking about a resistor or a relay, but cannot seem to find them in my car. Where would these be located so that I can check them? I have checked all of the fuses, and they seem to be fine. Thank you for any help!
