I have a Mazda 2014 GT 2.5L with fully automated dual zone climate control system. The air conditioner works on the passenger side and not on the driver side. And I know the driver-side air mix actuator is working fine. I am looking for idea on what could be the problem please.
As you can see in the attached table below (all temperature in F), I have placed 4 temperature sensors, one in each of the 4 air vents. I have set the dual zone temperature to different temperature with and without the A/C on. As you can see, when the A/C is ON and the driver side temperature is dial to low temperature, the air coming out on the left is by far not as cold as if I do the same for the right side. I have looked at the driver-side air mix actuator and I do see it moving when I change the driver side temperature dial from cold to hot. I have also looked at the passenger-side air mix actuator and I do see it moving as well. The air flow mode actuator is also working fine as I can change where the air comes out and it works fine.
From what I can see, there is only one A/C unit in the car, correct ? If so, what do you think the problem can be ?
