I have a clicking sound under the glove compartment. Looks like there's some kind of valve (see attached pictures). Several times a day it starts clicking On and Off like crazy, 3 - 5 times per second, or just a few times. It does it totally random. As if there's a some kind of loose connection that supplies the power to this electrical valve.

Larger pictures are attached below...



Looks like one side of the green hose connected to the white box mounted above (see another attached picture).

Does anyone has this problem?
Anyone knows anything about it?
Any way to check the source, where it suppose to be connected to?
