Hi guys.
I have 2014 LC. Lately when the AC is on I'm getting warm air from the 2 front passenger vents. The driver side and all rear are all ice cold.
After a while it gets cold and then warm again. Only happens on passenger front.

Any help would be appreciated

Based on your description, the R134a is slightly low; try ONLY add 1/4 to 1/3 can of refrigerant at the most (or as little as needed - when the passenger side becomes cold consistently). The system is very sensitive, in case over adding the refrigerant (the cold air will get warm again), properly recycle out/capture the extra r134a.

There could be other issues, can not tell per just the description above; need to know your hi/low garage pressure readings and responses under different scenarios. For now the easiest is to just add a bit of the R134a.

There is a problem with your servo motor. Use a diagnostic scanner like autel, launch or techstream to do servo motor initialization.
