I AM GETTING A KNOCKING SOUND WHEN I TURN ON THE AC IN MY CAR

2005 Nissan Quest • 95,000 miles

When I turn on the AC I get the knocking sound behing the center console. I stays on for about 2 minutes and goes away and comes back randomly. It is a constant knocking sound it never increases the knocking pattern when I accelerate. It even comes when I the shift is in parking.

You need to open it up and investigate to find out-could be an door actuator problem
