I have a 2012 GMC Sierra 1500 with dual climate controls. Sometimes the A/C blows cold air and then it will turn warm. The system is fully charged with coolant. I believe the blend door actuator for the driver's side is the culprit.

Where is the blend door actuator phsyically located under the dash?
