I have a 2013 3.5 ecoboost and my blower motor quit the other day. Than like a few hours later it worked again. Than a few days later it went out than came back on. Now it went out again and it's been 2 days. Has anyone ever had this problem? Is it the motor or a resistor. Or something else?

 

Automatic climate control or manual?

 

Not entirely sure. How do you know?

 

If all you need to do is set the desired temp you want on the display , and it controls the blower speed automatically, it's automatic. If you need to adjust everything from what ever setting you last chose it's manual.
If it is automatic there is a EATC electronic automatic temperature control module that controls blower speed and function, it sounds like it is malfunctioning.
