AAR or the AAV. Both will cause issues. You can take off the AAR and apply 12 volts to the plug. The unit should start closing down in less than 5 minutes. If it doesn't then it is bad. The unit will then only close based on the heat of the motor reaching the unit instead of the unit heating on its own to close the door. There is a bi-metal strip that heats up and closes the door. This is what goes bad.

If this is not the problem the AAV is stuck and or bad. This aids in start up around the AAR when you hit the key. It runs on the same circuit of hoses just is a valve that opens while the car is cranking and first starts. This is a common issue as well. Always has been on the SCs. The factory fix was to smash the valve in a vice 5mm. LOL, I am serious.
