How would I go about making my 94 es more quiet? It has a deep sound that makes it seem like a cheap old bucket. Also, I feel dumb asking this question, but the the right of the steering wheel close to were ones knee would be there is a small vent like thing, what is it? One more thing how exactly do you know if something is wrong with the unlock/lock function on the key? When I unlock and lock the doors with the button on the inside ten times the car beeps once, then a pause, and then twice. Does any one know what the problem may be? TIA
