Looks like this is a big issue with the connector. I have a 2012 Fusion with 55,000 miles. I am changing the resistor and harness/connector today. My problem was the blower was not working. Checked the fuse OK. I wiggled the connector to the resistor replaced the fuse and the blower worked OK. I thought the connector may have been loose. My wife drove the car the next day to work and she said it quit again and smelled something burning. I turned the blower on and it would not run so I pushed on the connector and it started. I let go and it quit. I pushed on it again and held it to keep it running. I had to let go because it would have burned my finger. I Disconnected the battery, disconnected the harness and removed the resistor. Found the two wires in the connector on the resistor from the blower were shorting together and burnt the connector and the connections to the resistor. I am using Motorcraft replacement parts. I am concerned the OEM parts are not adequate. 55,000 miles seem low to be having this problem. Other vehicles I have owned it was 100,000 miles or more and normally it was the resistor only and didn't pose a fire hazard. Not sure why the fuse didn't fail??? It is a 60 amp. Seems to me the #14 stranded wire should be protected at 20 amp?
