It seems like it coming from the passnger side wall of the console. It's vey slight and intermittent. Has anyone else had this issue or no what's going on? Thanks in advance.

 

There is a vacuum valve under the glovebox and it has been mentioned here as clicking a couple of times. Could that be it?

 

It's definitely coming from that area so that maybe it. It almost sounds like a relay engaging.

 

When the car starts up it will "check" for a passenger and if not detected, turns off the passenger air bag. That activity usually involves some clicking from behind the console. But once done, it should not continue.
