Idle speed control solenoid valve. Unsure of location but tried to locate info online but was not successful.

The clicking indicates one of the actuators is stripping a gear. I'd want to identify what one is making the noise before performing additional repairs.

Assuming you have dual mode control (not manual), there is a service bulletin for the 2011 Explorer that indicates a change in the mounting of the actuators along with reprogramming of the HVAC controller to resolve sporadic temperature control issues.

Realignment of the actuators and reprogramming probably reduces the total movement of the actuator so it no longer strips when it hits the manual stop of the door. It might be worth your time to perform the TSB and pay a dealer to update the HVAC software.

I posted a reply but it didn't show up.

I'd want to investigate the clicking to be sure you don't have another actuator that is stripping out. If one is, the HVAC controller can lose track of the door position and try to move to a default setting. Perhaps the actuator for the passenger side has a problem and is why it's going to the cold default setting.

There is a TSB for your 2011 Explorer that shows a modification of the actuator alignment along with reprogramming the HVAC controller to help prevent these conditions. It might be worth your time to perform the modification and then have a Ford dealer flash the HVAC controller.
