WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

PCM/ECM - A/C Disengage Reason: The scan tool displays the last reason the A/C compressor was disengaged.
PCM/ECM - A/C Off For WOT: The scan tool displays Yes or No. Yes indicates that the powertrain control module (PCM)/engine control module (ECM) has disabled the A/C compressor because the TP sensor signal is at wide open throttle.
PCM/ECM - A/C Pressure Disable: The scan tool displays Yes or No. Yes indicates that the PCM/ECM has disabled the A/C compressor due to excessive refrigerant pressure.
PCM/ECM - A/C High Side Pressure: The scan tool displays -103 to +3119 kPa( -14 to +452 psi). This parameter represents the A/C refrigerant pressure sensor voltage signal converted to pressure.
PCM/ECM - A/C High Side Pressure: The scan tool displays 0.00-5.00 Volts. This parameter represents the A/C refrigerant pressure sensor signal.
PCM/ECM - A/C Relay Command: The scan tool displays On or Off. Represents the PCM/ECM commanded state of the A/C compressor clutch relay control circuit. The A/C compressor clutch should be engaged when Commanded A/C displays On.
PCM/ECM - A/C Relay Circuit History: The scan tool displays OK, Open, Short or Invalid State. This parameter indicates the state of the driver circuit for this device.
PCM/ECM - A/C Request Signal: The scan tool displays Yes or No. The PCM/ECM uses the A/C request signal in order to determine if A/C compressor operation is being requested by the HVAC Control Module.
HVAC - A/C Request: The scan tool displays Yes or No. This states that the A/C request is being made by the HVAC control module.

HVAC - Aux Temp Dr. Motor Command: This data indicates the value of the commanded door position.
HVAC - Evaporator Temp Sensor: The scan tool displays 0-255 counts.
HVAC - Evaporator Sensor: The scan tool displays -40 to +215°C (-40 to +420°F). The output of the A/C low side thermistor.
HVAC - Mode Status (Display: Recirc/Vent/Mix-Blend/Floor/Bi-Level/Defrost): This data indicates the mode selection knob position.
HVAC - A/C LED: The scan tool displays on or off. This is the status of the LED.
HVAC - Rear Defrost LED: The scan tool displays on or off. This is the status of the LED.
HVAC - Driver Heated Seat Status: The scan tool displays Off/Low Heat/High Heat. This is the status of the heated seat switch.
HVAC - Passenger Heated Seat Status: The scan tool displays Off/Low Heat/High Heat. This is the status of the heated seat switch.
HVAC - Blower Motor Switch Position: The scan tool displays Off/On But Not High Blower/On and High Blower. This is the status of the Blower Motor switch Position.
HVAC - Aux. Blower Motor Speed Command: The scan tool displays 0-255 counts. This is the auxiliary blower motor commanded speed.
HVAC - Aux. Blower Motor Switch Position: The scan tool displays Aux/Off/1/2/3/4. This is the status of the Auxiliary Blower Motor switch Position.
HVAC - Aux. Blower Motor Speed: The scan tool displays 0-255 counts. This is the actual status of the Auxiliary Blower Motor speed.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
