I have a 2011 4.6, and I went into work and it was working fine. The temperature dropped to 6 degrees today and when I left work a blower motor stopped working. In my climate control screen, it shows that the fans are all the way up or what not, so I am wondering where to look for that reason. I looked underneath the hood and there is a 40 amp relay or something that doesn't come out and then there's just the great big relay thing that says blower underneath the fuse cap map diagram. Anybody could help me that would be much appreciated.
