My new 2019 CX5 GT has a fault with the air climate control. When set to Sync the passenger vent blows air a lot warmer than the driver's side. Anybody else having this problem? Thanks

 

Air mix actuator might be broken, but still under your Warranty, -see below.

CAUTION:

• If the lever position exceeds the operation range shown in the figure, the circuit in the actuator could be damaged. Always perform an actuator operation inspection with the lever movement within the range shown in the figure.
  

Driver-side



1. Connect battery positive voltage to air mix actuator terminal C (or B), connect terminal B (or C) to ground, and then verify that the air mix actuator operates as shown in the table.

• If the operation condition is not normal, replace the air mix actuator.

2. Verify that the resistance between terminals F and G, E and F matches the air mix actuator operation as shown in the graph.

• If the operation condition and resistance are not normal, replace the air mix actuator.

Thanks I actually saw a video in Youtube demonstrating how to replace the actuator and even told Mazda but either they're too lazy to perform a real test rather than just placing their hands on the vent or they have no intention of going through the trouble. I found someone else in facebook with the same problems and she's been back to Mazda 4 times and now the problem is worse so I wonder if it's fixable on the 2019 CX5 model
