Wondering if anyone here can identify this plug- the unplugged one. it's alongside the driver's side wall, behind the washer reservoir and next to the p/s unit. Came out to my car today, battery was drained, idiot lights would barely light up dimly, no crank, and all i hear is this plug buzzing. Took me forever to isolate it- I actually thought i shorted out the alternator and it was buzzing....found out the hard way it wasnt.
