Interesting. My 2013 mustang gt blew a fuse #7 and I replaced it, then it blew again shortly after and after changing the fuse again the motor came on and was screeching. I figured bad motor so I replaced it and the original fuse, I did notice inside the connection had some burn damage so I put some terminal grease and plugged it up. It ran for a week with no issues however I noticed while sitting in traffic with my AC on it started to climb in temp and ac slowly stopped cooling similar to before so when I pulled over, I noticed the fan motor wasn't working, I left it alone for about 2hrs and cranked it back up and started driving and had no issues, when I drove back to my house with no ac (15minutes away) I pulled in and the fan was on high running. I turned on AC to see if it was causing the issue but the car ran the way it was supposed to. I'm not sure what's going on. The fan motor is new and motorcraft. Car has 125kmiles
