Reported by Papagiglio for the Cadillac DeVille

under the front left fender/bumper area, there is a electric pump that pushes air into the catalytic converter. It runs for about 45 seconds when you start you car and once in a while there-after. The bearings went out in mine and I tried to repair it, but ended up replacing it. After 8 months, the new one failed. The GM dealer warrantied it and I replaced it again, which now has stopped working again.
