That'* great to know.
So if I use my control panel in "Manual" Mode with a particular temperature selected, how does it know to modulate the air mix actuator to maintain the selected cabin temperature if it doesn't use that sensor (near the cigarette lighter)?
My next step is to observe the actuator, then.
Curious. Is the 90 deg setting some kind of a "limp home" mode that drives the actuator manually full hot regardless of the sensor? The air temp got instantly HOT when I selected 90 deg, then cooled off rapidly when I selected 85 deg or any lower temperature. (The actual interior temp was about 60 deg during this test)
I am trying to learn how the digital climate control "thinks" to make its failure more easier to understand.
