That does make sense. I will check into it...thanks! Today, I got stopped by a cop, he didn't like how fast I was accelerating from a stop light. I told him, "until you drive a beefed up Ram Cummins 5.9 12V, you just can't understand. This thing is a beast, hard to keep my foot out of the pedal!

Got an update. I went ahead and cut a square section out in the HVAC housing, in front of the heater core, to see if the blend door was good. Turns out it is working fine. I firmly believe now, that I have some blockage in the cooling system, feeding the heater line out, going to the heater core. I am going to take it in this week to a professional heating/AC shop, to get them to flush the system.

Guess my write up didn't get posted.
Blend door motor failed so I found a replacement on FleaBay for $6 compared to the entire module for $130+
Found a replacement motor p/n# RF-370CN or in this case, RF-370CH
Re-installed and all is working again... hopefully this will help!
