Okay- this is a Probe question, but maybe you all could help me out. When I start may car, I have a quiet "buzzer" go off for about 3-4 seconds, and then quit. While running the car, it'll come on for maybe a second, then go away. If I drive the car 15 minutes, it may go off 2-3 times. What is this? It sounds like it's under the dash, like a seatbelt buzzer, but it's really wierd. The car runs fine. Any clue?
