I have searched the site; however I can not find a post asking my exact problem with the auto climate control in my truck.

My issue is:

My auto climate control is not being auto. When on, I get high heat output and the fan is on full bore. So I have become the auto function. When I am cold I turn the heat on. When I get too hot I turn off the heat.

Any help or a direct to a earlier post would be appreciated.

I have a 2009 F150 Lariat and I just crossed over the 100,000 mile mark.
Thanks
