AC blows cold on drivers side but hot on passenger side

Hello, sounds like a possible failure of a temperature blend door actuator on the passenger side - not turning the door to funnel cold air through those dash vents when desired and requested. Hands on testing is needed - often times when trying to adjust a clicking noise can be heard with a faulty motor. The blend door itself could also be fractured in some cases, so fingers crossed it's just a motor.
