The fast clicking noise is intermittent and lasts only a few seconds but is starting to last for up to a minute now.

Yep, this is common when one of the blend door actuators for the HVAC system has gone bad, can you tell if something is not working correctly like the vent or temperature controls? Here is the location of the blend door actuators so you can see where the noise might be coming from.

1. Mode control actuator [LH]
2. Mode control actuator [RH]
