HVAC Problems
2005 having strange HVAC module problems. First hooked up Tech2 scanner and HVAC module not found. A/C clutch not engaging. Rear defroster not working. HVAC module display is just fine, blower motor control is fine. temp display is present and able to adjust air output. When you you shut car down HVAC module stays powered up and all controls that work stay working. Have to disconnect battery to turn module off or dead battery in about 2 hours. Any thought would be greatly appreciated.
