HVAC Control Panel 2013 GMC Sierra

HVAC Control Panel 2013 GMC Sierra

I'm looking for some feedback and hopefully I explained this properly.

On my 2013 GMC Sierra after the truck has warmed up I will only get lukewarm air blowing out of my heater vents and the only way to get it to blow out hot and fix it until it's next cold start where the same thing will happens again, is by constantly moving the middle dial as shown in the picture back and forth from hot to cold hot to cold several times and then it starts to blow out it's normal hot air without any issues for the rest of the day until like I mentioned on its next cold start the next day where I have to repeat the same process in order to get it to blow out hot air.

I'm not sure if it's the panel or a blend door actuator.

Hopefully that made sense in my explanation any feedback would be great

ThanksImage

My guess would be mode door actuator. I have an 11 had similar issues but on cold side. Replaced actuator all good. I was able to access by pulling out the upper glovebox and using a flexible wrench. Good luck.
