2010 wk 3.7l laredo

hey guys i'm new here and I see that this is kinda an old thread but, I recently purchased a 2010 laredo wk w/ 3.7l v6. the problem started by me turning my red to blue temp on control knob from hot to mild and then when i went to turn it back to hot it would not work and all i got was cold air even when my temp. control knob was all the way in the heat direction.

I then noticed that my car was never getting up to warm running temp. so I change the thermostat hoping that would fix my no heat issue. It did not fix my heat blowing cold air.

Next I removed my glove box and in side right behind(towards engine compartment) the climate control unit i found where the little plastic piece that I can manually turn with a screwdriver to get the heat to work. upon learning of the scenario i then proceeded to test my other knob the changes what vents are being used, that knob still functions and i can see a similar "plastic piece" slowly turning as i adjust the position of the knob.

Does anyone know what exactly my problem is?

I know its something with the blend doors and blend doors actuator and the control knob for those parts.
