I do not have the temp control set to dual, so both sides are the same. I drove for 4 hours to day with no problems, I also carried out a system check, with no fault codes present.
Below is some text from the Lexus repair manual I have.
An automatic air conditioner system which provides enhanced air conditioner comfort according to the occupants' senses has been newly adopted.
In the previous automatic air conditioner system, the Ecu determined the required outlet air temperature and blower air volume in accordance with the calculation formula that has been obtained based on infor- mation received from the sensors.
However, because the senses of a person are rather complex, a given temperature is sensed differently, depending on the environment in which the person is situated. For example, a given amount of solar radiation can feel comfortably warm in a cold climate, or extremely uncomfortable in a hot climate. Therefore, as a technique for effecting a higher level of control, a neural network* has been adopted in the automatic air conditioner system. with this technique, the data that has been fetched under varying environmental conditions is stored in the Ecu, which effects control to provide enhanced air conditioner comfort.
*: Neural Network =Is capable of effecting complex control by artificially simulating the information processing method of the nervous system of living organisms in order to establish a complex input/output relationship that is similar to a human brain. An intelligent swing register, which controls the orientation and the angle of the front center register, has been newly adopted for improved comfort.
