SOURCE: air conditioning

On a w body car with a single temp adjustment control (not a dual zone) your problem should be a low refrigerant charge. Due to the design of this evaporator, a low refrigerant charge will cause the furthest areas from the inlet and outlet hoses (the drivers side) to not remove the heat from the incoming air. This allows the air on the drivers side to be outside temp but refrigerated on the passenger side. In cars with Dual Zone controls you must not only verify the refrigerant charge level, but also check the mode doors which control the air flow and regulate the temp. To check the refrigerant level do not use pressure gauges alone. Verify a proper charge level by checking the temperature of the two aluminum lines going in to the firewall of the vehicle. With the A/C set to high the temperatures should be within 5 degrees of each other. If not, then there is a charge issue. I hope this helps

SOURCE: 1999 pontiac grand prix gt dual climate control not working prope

The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.
Regards,

Two things can be the problem,first,try adding ,a little freon,if it is low,it will only cool one side,then if this does not help,there is a door actuator motor that controls this,it could be not working,the dash has to come out to replace this actuator motor,if this was at all helpful,please rate,thank you.

02Park Ave is blowing warm air on passenger side, but not drivers side nor windshield or heater


Are you able to control the driver side air temperature at the dash registers? If not and you can control the passenger side of the dual climate system then you have an issue with the air temperature control door (moves between the heater core heated air and the AC evaporator cold air stream) deep inside the dash or the electric actuator that moves it or in most cases both.

Dual-Zone AC Problem


My guess is that one of the hose's has a leak and needs to be replaced. A mechanic can run some tests to check if that's the case. Best of luck.

Cold air comes out driverside but not passenger side


if it has dual climate control -- drivers and passenger temp control-----
it could be a temp blend actuator, if it has only one temp adjustment,
it could be a door concern inside the plenum behind the inst panel.

Impala has dual climate control. AC blows cold on


with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!
