After a Sunday morning drive, I came home, parked, and when i pressed the lock button on the remote, there was a very high piercing sound (almost like a dog whistle) that would not go away. It lasted for about an hour, and then my battery was dead and nothing electrical works. Any ideas as to what may have happened? Thanks in advance.

Have you installed any aftermarket speakers, or hard wired any electronic (ie. radar detector)?

graphrackr

Thanks for the response. NO, I have not installed anything electronic.

are you sure you didnt leave the lights on? :/ It beeps at me when i turn off the car and the lights are still on (when i dont use the autolights)

graphrackr

Absolutely positive. This sound was much different than the light beep.

Had my problem fixed today. It was the driver side window motor that killed the battery. When I had the car jump started today, the windor rolled up and down automatically at least 20 times, so I drove straight to the dealer. Service guy said he's never seen that before. Battery and motor replaced.
