Hello, I am trying to determine if my Auto climate is woking correctly. I have 2012 RX350 with NAV.

I believe when I first got the car that when the Auto button was pressed, the AC light (in the climage screen) came on, and was always on. It could only be turned off by powering the fan speed to zero.

However, I now have this situation:

Auto A/C Mode On (in custum settings)
Climate control is in manual mode with AC light on.....when I press Auto the A/C light turns off (cannot be turned on by repeated presses of auto)

Auto A/C Mode Off (in custum settings)
Climate control is in manual mode .....when I press Auto the A/C light stays in current condition either on or off.

Summary: pressing Auto no longer turns on the A/C switch (and I believe it used to)

I believe it has sensors and will turn off Automatically if ambient temperature is cold..has sensors for humidity also I believe.

Thanks.

One more question.....

should the A/C light come on when the front defrost button is pressed. I thought it should, but mine does not. Is dehumidifying not related to the A/C button?

ok, so figured out through research and experimenting, that the AC did not come on when auto was pressed because outside temp was below freezing. when above freezing, even though still very cold, the AC comes on when the auto is pressed. That is solved

However, stil no AC coming on when the defrost button is pressed.
