Radiator fan not working

What is your question?

One of the radiator fans not working in my 2013 Chrysler 200. I took out the fuses and relays and checked them with a multimeter and it seemed fine, not sure if I did it right but they seemed to check out. Then I decided to switch the two wired connections to the fans around and the one that was previously not working started working. So it seems to be something with the wiring. So I’m not quite sure what to check next.

What makes this problem better or worse?

Switching wiring makes one work and one not

How long has your 2013 Chrysler 200 had this problem?

Few weeks
