Wire running to under-side hood
I noticed this wire leading from behind the glove compartment to the
underside of the hood. Please tell me why this cable/line is there and what it
is used for. I have had my car for over a year. I don't perform maintenance
myself, but I check under the hood frequently, and I just noticed it today after
a recent visit to a dealer. It seems like it was fastened to the underside of the
hood because there is a broken clip loosely attached to it near the passenger
side quarter panel.
