Temperature knob doesn't work 09 2wd

[Ferris Bueller]

When I turn the temperature control knob it changes nothing. I carry a lot of tools inside of the truck. Could they bump up against anything to effect this? It is in my 2009 2wd 2.3 with manual tranny and A.C.

Only if you stuff the tools inside the dashboard.

I will have to "go in" and find out what is wrong. Its hot one day and cold the next.

Check your 'blend door' to see if it's broke.

I know the earlier year Ford blend doors were hinged on plastic, which cracked and shit, causing it not to work like it should.
