Sixto nailed this one. The electrical contacts in the "ignition" switch (Well, its a habit I still call them ignition switches!) gets worn and makes a flaky path to the instruments and buzzer and stuff. What will happen eventually, if you don't replace it, is the car will not even start, so you should probably learn where the three connection terminal is on the drivers side fenderwell, near the battery, and which pins to place a jumper wire on to manually activate the starter motor so you can drive the car when the key switch fails completely. I lived with a car that had a flaky key switch for a couple of years before I decided to replace the thing, along with a new lock cylinder. Its so nice to have a new lock and key in place of the 21 year old worn out ones
