What is this?

What is behind this panel? When I start my car it sounds like a motor priming for about 5 seconds behind it??

What you hear should be the fuel pump priming.

Is that where the fuel pump is? Though it was in the tank?

It is in the tank. Are you sure it's coming from that panel?

Pretty sure. What is behind the panel? I don't think it's for the rear hvac??

I actually do think there is rear heat actuators in there... Not positive though.

Rear air?

Rear air?

That's a possibility but it comes on everytime you start it, even with all the hvac off.
