Stoln Posted February 5, 2017 Report Share Posted February 5, 2017 I have a Sel AWD 2013. I use Auto feature all the time. I am getting what I say are grunting noises from the HVAC system from time to time. I can say it is consistant in the winter but other seasons not sure as I observe it now. Has any one shared the same issue? I don't want to go to the dealer to be charged for something they cannot find. Quote Link to comment Share on other sites More sharing options...
omar302 Posted February 5, 2017 Report Share Posted February 5, 2017 It is probably one of the door actuators, to figure out which it is manually change HVAC settings & listen for the noise. For example, change from defrost to front registers to floor. Try fresh air/recirculate, and check each side temperature settings (driver/passenger), go from full cold to full hot. 1 Quote Link to comment Share on other sites More sharing options...
