Been having an issue with the air cond. system on my 2017 Accord Touring. When I turn on the a/c, the far-right (passenger) vent blows cold immediately. The center-right vent is cold, but not as cold as the passenger vent. The center-left is a little warmer, and the driver vent blows ambient air. The driver side vent eventually blows cold, but nowhere near as cold as the vents to the right. I've noticed this for a couple of years, and in Sept. 2019 (while still under warranty), I took it to the dealership and they injected die into the system, and also evacuated and re-charged the a/c/ system. I took it in a couple weeks later so they could see if there was any die leaking, and there was not. Any thoughts on what might be causing this issue?

 

Is this an automatic AC with left and right temperature zones??

 

Yes, but both left and right are set to Low.
