2007 AURA XE
Default HVAC not functioning

A couple weeks ago I took my Redline out for the first time since November. And since I live in Ohio the temp fell from a balmy 70F+ to 50F+ in about five minutes. Which meant I turned on the heater. It had one setting - Hellfire. The other day when it was 80F+ I took it out and switched on the A/C. It had two settings - Arctic and, once moved from the first click, Hellfire.
So before I take Skyler to Fumblefinger Bros. GM to be looked at does anyone have any idea what's going on and/or how to remedy?
Thank you.

Some easy things to check before visiting GM or a reputable ac repair shop.

1- check for a blown ac fuse.

2- If the fuse is fine, either have someone turn on ac while you observe the ac compressor engage with a metallic click or listen carefully for it as you turn on ac with the engine idling. All ac compressors use an electric coil for clutch to engage the free spinning pulley. The clutch plate moves a few thousandths of an inch when engaging and usually makes a loud click from metal clutch to metal pulley contact. If you do not see or hear the clutch engage, this may be loss of refrigerant issue - a leak releasing refrigerant, oil and dye.

Normal wear and tear occurs with many ac systems failing from inevitable damage with a leak occurring. When enough refrigerant is lost, a pressure sensor detects the loss and sends a disable signal to the ecm to disable compressor operation. The sensor protects the compressor from self destruction. GM made it easier for mechanics and diyers when dye was installed at the factory. Dye mixed with refrigerant oil circulates throughout a system so any break or weakened seal releases refrigerant, oil and dye with dye marking where damage occurred. An inexpensive uv blacklight will make fluorescent dye glow to show where damage occurred. Removing one or both service valve caps should reveal some refrigerant oil and dye (greenish yellow).

If this doesn't work you may have a bad actuator (or two). The other possibility is that you need to add a resistor to bring the voltage back in line to where it should be.


Actuator Recalibration
When replacing an air temperature, mode, recirculation actuator or the HVAC control assembly, the following calibration process needs to be performed:

Important: Do not adjust any controls on the HVAC control assembly during self-calibration. If interrupted, improper HVAC performance will result.

1) Turn ON the ignition with the engine OFF.

2) Turn the Temperature dial all the way to the right.

3) Turn the blower control dial all the way to the right.

4) Turn the mode position dial all the way to the left.

5) Simultaneously press and hold the A/C and Defrost buttons until the LED's start to flash.

6) Once the LED's stop flashing, calibration is complete.
