I've noticed more outlet temperature difference in my 2017 Ridgeline than any other vehicle with automatic climate control that I've ever owned. The exception was a '99 Buick Regal that later in its life was always warmer on the passenger's side due to the blend door motor. For example, this morning on my way to work it was cool and sunny outside. All three zones were set at 68°F. For the duration of my commute, the driver's outlets blew cold air, the passenger's outlets blew cool air, and the rear outlets blew very warm air. For many years, various Honda/Acura models with navigation (including the Ridgeline) use the GPS to report solar angle to the climate control so it can tweak settings to compensate for sunlight entering the cabin. However, I notice the driver's side outlets are always cooler than the passenger's side no matter where the sun is or which direction the vehicle is traveling. The vehicle has no problems cooling off. The air conditioning system seems to work just fine, but it bugs me that every outlet blows a different temperature, which is most noticeable once the cabin has reached setpoint and the system is maintaining that setpoint.
