Question about 2004 GMC Envoy
Heater Mode, Bi-Level Mode, and Defrost Mode are fine but in full A/C Panel Mode or in AUTO when Temperature warms up and A/C is trying to provide full cooling through the Panel Vents, there is a continuous snapping noise coming from inside the dash. Suspect the Mode Door Actuator or something blocking the door. Can this be accessed without breaking into the refrigerant system?
Yes you should be able to follow the vent system and see where the outdoor /indoor flap is . this flap may be what you hear
