Wow I have the same problem with my heater not working at different temps exact for max heat. This is on a 05 5.7 l with the auto a/c controls. Have any of you got a fix for this if so please let me know.

my 05 WK has the same issue, I did not notice it until it started getting real cold, but it blows cold air unless at the max settings, which then blows very hot. WHile it is great that the heat blows so hot it gets a bit uncomfortable when running in the auto settings.
Is it me or are there a LOT of electrical problems related to the 05 WK's? It seems most all have the flashing dash lights, faulty heat controls, random window motor problems, and door locks malfunctioning. Not to mention the weird codes which seem to be thrown. If I did not already have one, I would think it is something to avoid purchasing.

Have had the same thing going on. Recently found that if the dial is on a number not the red dot when I start the vehicle it seems to work ok and able to control the temp. Maybe something to try. Have also heard the blend doors can go bad and need to be replaced.
the blower motor resistor? My blower motor will change speeds just fine, its just the temperature control/blend door related stuff. If I take her to work tomorrow in the truck I will try putting it on the middle and keeping it there and seeing how it goes, I am pretty sure mine will cycle to blowing cold like way to quickly. I need to take it to the dealer and have the new flash I think.
