My 2009 f150 was blowing heat out one side and cold out of the other. I replaced the door blend actuator, then it stopped blowing all together. I just replaced the blower resistor, which did not work. It still blows cold out of the seats also. Any advice where to start next would be helpful.

 

Are you sure you didn't forget to plug something in?

 

I was thinking that, I double checked this afternoon and I couldn’t see anything that was unplugged

 

Did you check the fuses? It sounds like you may have blown one.

 

Turns out it was the blower motor, I replaced it and it’s good to go now. It is odd that it went out at the same time as I was replacing that other part. But thanks for the replies y’all

 

Mystery solved!

Good job!
