2002 Buick Century climate control

On my Buick Century 2002 there is a passenger climate control. Whether this is in use or if just the regular A/C is on the driver's side is warm and passenger's side is cold
Anyone out there have any ideas.

This is typical of a loss of refrigerant in your a/c system- the evap is cooled on entrance side and not enough refrigerant to cool exit side- hence the difference in temps side to side of car.

Find and fix your a/c leak, evac and recharge to factory spec.
