2000 Cadillac Deville V8 Front Wheel Drive Automatic 95000 miles
When I start the car, a knocking sound is heard from under the dash. After a while (30 seconds), the noise stops. I suspect it may be a damper that is knocking inside the ductwork and disappears after the vacuum increases. How do I repair this?
have the same problem?
