    Comp was working as it should and air was cold. I checked the site glass and saw some bubbles while comp was running. when i shut the AC off the site glass was white,, so air or moisture is in line , probably need to evacuate system and recharge. I just brought it to dealer, thanks for response.

When it gets warm , open the hood and watch the ac compressor , is the clutch still engaged and the front of ac compressor spinning , is the large tube out the back very cold , the other tube should be hot or warm.
if the air is warm but the ac is working correctly under hood then you have a issue with the vacuum controls on the inside of car.

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: Front air condition does not blow cold. Rear air condition does

sounds like a damper door in the front not working properly, these are actuated by the front temp control, the door is operated by either a manual cable, and electric actuator, or vacuum. I hope this helps you zero in on your problem. Merry Christmas

Have you checked the coolant level? If it's low, it will result in diminished heat, and could be the problem.

SOURCE: How can I fix my air conditioning?

You should check to see if the a/c heater fan motor has power first. If it does, then the motor is most likely bad. If there is no power there then the fan relay, usually mounted on the firewall in engine compartment may be the culprit. They have been known to get very hot and start to melt internally, causing failure of power to the fan motor. I have replaced three of these relays and finally had to replace the socket connector as well.

SOURCE: air conditioning blows cold on drivers side but

dodge has dual blend door actuators on the air box. you have to pull the dash board assembly out to access the passenger side door actuator. it calls for 5.8 hours to do this job. you also have to evacuate and recharge the ac system.

Tip

Tips for operating Air conditioning system on Toyota Hilux and someother...


To cool off your Toyota after it has been parked in the hot sun, drive with the windows open for a few minutes. This vents the hot air, allowing the air conditioning to cool the interior more quickly.

Make sure the air intake grilles in front of the windshield are not blocked (by leaves or snow, for example).

On humid, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

Keep the area under the front seats clear to allow air to circulate throughout the vehicle.

On cold days, set the fan speed to high for a minute to help clear the intake ducts of snow or moisture. This can reduce the amount of fogging on the windows.

When driving on dusty roads, close all windows. If dust thrown up b the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the in intake be set to FRESH and the fan speed to any setting except "OFF".

If following another vehicle on a dusty road, or driving in windy and dusty conditions, it is recommended that the air intake be temporarily set to RECIRCULATE, which will close off the outside passage and prevent outside air and dust from entering the vehicle interior.

HEATING

For best results, set controls to;
Fan speed ---- Any setting except "OFF"
Temperature----Towards WARM (red zone)
Air intake ---- FRESH (outside air)
Air flow ---- FLOOR
Air conditioning ---- OFF

For quick heating, select recirculated air for a few minutes. To keep the windows from fogging, select fresh after the vehicle has been warmed.

Press the "A/C" button on for dehumidified heating.

Choose floor/windshield air flow to heat the voltage interior while defrosting or defogging the windshield.

AIR CONDITIONING

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

For quick cooling, move the air intake selector to recirculate for a few minutes.

VENTILATION

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

DEFOGGING

The inside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone) to heat; COLD (blue zone) to cool
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- ON

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

On humid days, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

DEFROSTING

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

To heat the vehicle interior while defrosting the windshield, choose floor/windshield air flow.

2000 Yukon denali, recharged air conditioning systemt, blows cold air in the rear, warm air up front?


Hi, Sounds like your actuater for your heater box damper is bad. Its munted under the dash over the center hump. you will have to remove the cover that goes the length of the heater box to find it. The actuater motor should move back and forth with the temp knob going from cold to hot.

Low refrigerant charge or a sticking blender door. Check the suction line for temperature. A cold tube means that the charge is fine.

Try changing the lower temp sensor in the air duct on the drivers side. I bought one and never replaced it. before the part arrived I took the lower sensor out and taped it up and put it back under the dash... not in the air duct housing were it belongs. believe it or not it works so well I did not even see a need to change the thing.
