Cold air in the right side ambient temp in left

HVAC , air temp CAB
or engine air temp IAC?
say HVAC< if climate control options in heater or / AC fails.
tell the problem first so we now where your looking, thanks
why do you think you have one, at all (yes on newer models)
not told they why? scan tool scans shows i fails? How?
right side behind glove box right LHD car. USA



heater box seen.
best I can tell the photo above is 2005
and 1999 had no such thing, no climate controls then.
so post a real problem and we tell you tests to learn the TRUTH
of what is wrong, called DIAGNOSIS
is cold air AC failng
is heater failing or blower speeds dead.
or modes fail, (heat/cold/blend, recirc)
what;'s up doc?
are you cooling or heating the cab, or just defrosting?

Manual or automatic climate control ?
Have you had the HVAC control panel checked for DTC'S - diagnostic trouble codes ?

Air Temperature Sensors
The air temperature sensors are a 2-wire negative temperature co-efficient thermistor. The vehicle uses the following air temperature sensors:
• Ambient Air Temperature Sensor
• Inside Air Temperature Sensor Assembly
• Upper Left Air Temperature Sensor
• Upper Right Air Temperature Sensor
• Lower Left Air Temperature Sensor
• Lower Right Air Temperature Sensor
A signal and a low-reference circuit enables the sensor to operate. As the air temperature surrounding the sensor increases, the sensor resistance decreases. The sensor signal voltage decreases as the resistance decreases. The sensor operates within a temperature range between -40°C (-40°F) to 101°C (215°F). The sensor signal varies between 0-5 volts.
The input of the duct air temperature sensors are different from the ambient and inside sensors. The HVAC control module converts the signal to a range between 0-255 counts. As the air temperature increases the count value will decrease.

• DTC B0174 Output Air Temperature Sensor (Upper Left) Circuit Range/Performance
• DTC B0179 Output Air Temperature Sensor 2 (Lower Left) Circuit Range/Performance
• B0414 is for the left air temperature actuator.
B0408 is for the left air temperature actuator.
DTC B0989 Output Air Temperature Lower Sensors Correlation
The HVAC control module monitors the upper left and upper right duct temperature sensors when the mode switch is in the VENT or BI-LEVEL positions. The HVAC control module monitors the lower left and lower right duct temperature sensors when the mode switch is in the DEFOG, FLOOR or FRONT DEFROST positions. The duct sensors are used to measure the temperature of the air exiting the ducts to help maintain a consistent cabin air temperature. These duct sensor inputs provide the HVAC control module a way to determine if the engine needs to be started to maintain a specific air temperature. If an upper duct sensor circuit failure is detected the HVAC module will not request an engine start to help cool the cabin. A lower duct sensor circuit failure will not prevent the engine from starting.

Your best bet , take it to a qualified repair shop .

code p 0072 refers to outside air temp sensor ( ambient temp sensor--low input===causes ---wiring short to ground, outside air temp sensor ---ECM
thee has to be an ambient temp sensor as that reports the temp to the ECM to adjust the air/fuel settings for cold starts
it could be in the MAF/VAF sensor area

If you put the can freon in you probably did not equal out the high side as well. The gauge on the can freon won't help you. You need the professional gauges to get it right. Sounds weird but That's what happens on GM's when the pressure is not correct for the ambient temp.

is the evap canister cold? And is the pump turning on and of with the clutch on the ac pump? Also could be a electric motor that controls the flaps in the dash that control hot and cold. I have found that sometimes using the can freon will not put the pump in operating range for the ambient temp on the high and low side. There has to be a certain level on both sides that works with the outside temp!
