What is your question?
Just serviced AC . 1.45#s low on freon. Setting to “dual” on control doesn’t change it. Both sides set at 69 degrees on AC setting. Where’s the relay/switch that would control the heat/ac on the passengers side?

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. With the dual zone climate control system, each side has a temperature blend door actuator, which is an electric motor that adjust the temperature of the air to what is being desired as set. Sounds like the passenger side actuator may not be working properly. Worse yet, the plastic gear in the plenum box itself could be stripped or the plastic box fractured. Hands on inspection is needed to check the motor and where it mounts to. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
