strange - sounds like an electrically operated accessory of some kind is broken. Hard to say without hearing it myself. You need to get it up on a lift and hit the key while someone else watches and listens below. Also, try posting this in the General Maintenance and repairs section - it will probably get more exposure there.

Yeah - no prob. Are you blowing any fuses? I would start pulling fuses one at a time until you isolate the circuit. Sounds like a wild electrical short of some kind is zapping the battery. Usually problems this severe are liked to major electrical connection problems. Did you do any work on the car just before this happened?
