Summary
Some customers may complain that 1) the air conditioner is not cold enough or that 2) the cabin is cold, but the fan speed stays on high and there is noise coming from the blower motor. The following may be the causes: 1)The A/C compressor ON/OFF control is not operating correctly, causing a problem with the air temperature control. 1)The air conditioner may not be cool enough due to inadequate amount of the refrigerant, due to leakage or overcharging. 2)The control of the amount of air blown is incorrect. To eliminate these concerns, the front and rear climate control unit software has been modified to optimize the amount of air blown and the A/C compressor ON/OFF controls.
