I have a 2011 MKS ecoboost with about 71k miles. Just started getting clicking noise in climate control system - either when car is first turned on (with climate control on) or when restarting climate control. The noise is coming from the passenger side, just below the glove compartment. It makes 3 or 4 clicks, then stops. Other than that, climate control seems to work fine. Does anyone have any experience with this?
