2004 Rx330 Auto Climate Calibration

Recommended Posts

Hi,

It seems like the auto climate control in my 04 RX is always on med speed. Let say the ambient temperature is 26C , I have to always dial the setting to 32C in order to turn down the fan to face and feet (which I considered as equilibrium setting).

Anyone know if this can be adjusted (I think there is some customization available in CBEST, but can I DIY).

Also as a side ntoe... how do you now if one has the latest ECU software patch ( for fixing the hesitation issue)... other then doing to the dealer for a service history

Thanks.

The blower will always run at a reasonably high speed until the cabin has cooled to or very near your temperature setpoint. Then the blower speed should be automatically lowered to a mere whisper, Unless the sun is shining brightly on the solar radiation sensors. I sometimes lay a book or some object over the sensor (my 2001 has only one) to combat this problem.
