Good evening,

Can you hear the mode door move when you command cold to heat and back?

Common issue is the blend door actuator. Do you have dual controls? driver and passenger side control?

I translated this question to mean that when the A/C was being used the engine operating temperature quickly began to rise, all was okay when using "heat". Maybe that's just me?
