Hey guys:
My Automatic Climate Control fan speed doesn't change speed in the Auto setting. Well, it does in one aspect. When you move the lever through the temperatures, it will lower speed in the middle and then speed up again at the extremes. That is how the shop manual tells me to test the ATC servo.
On the other hand, the feature where it is supposed to start on high and then slow down eventually automatically as the temperature reaches a set desired level is not there. The Auto setting is more like medium speed forever when the temperature lever is not moved. Meaning it starts and stays on medium even when the car starts a journey as hot as Hades inside from the baking sun and the Auto is selected. My understanding is that the fan speed should be hands free, always start on high, and work itself down as the car gets to the desired temerature. The high setting is clearly always faster than Auto when I start the AC and I end up choosing high instead of Auto.
I've already replaced the temperature sensor some time ago to see if that helped. Could the culprit be the High-Medium-Low-Auto switch or the ATC? servo?
