Air conditioner blows cold air on passenger side warm air on drivers side

SOURCE: heat works on driver side, passenger side blows cold air.

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

SOURCE: 1998 Buick Century Air Conditioner not blowing out cold air

My 98 Buick Century was doing the same thing. Up here is the north we have Canadian Tire. Went in there picked up a aircon recharge kit called RED TEC 12A hole kit costs $40 cnd I put 1 can in on the low pressure side which is the only fitting that the filler would fit on and now I have 33 degree air coming out of the drivers side and a couple degrees colder from passenger side.
I am sure you guys have something like Canadian tire down there you might even try Wallmart.

SOURCE: a/c blows hot air on drivers sde

The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.
