Why is cold air blowing out on driver side on your 2004 Acura TSX?

Cold air blowing from the driver side of a 2004 Acura TSX could indicate an issue with the climate control system, possibly a malfunctioning blend door actuator that controls the flow of hot and cold air. It may also stem from low refrigerant levels or a refrigerant leak affecting the air conditioning system. Additionally, a problem with the heater core or a clogged coolant line could cause uneven temperature distribution. It's advisable to have the vehicle inspected by a professional to diagnose and resolve the issue.
