Two problems related to alternator/generator/regulator have been reported for the 2004 Chevrolet Avalanche. The most recently reported issues are listed below.
Driver side power window stopped working, locked in closed position. Nothing leading up to it. Happened in oct 2007 (1 month out of warranty). Finally took to dealer for repair in oct '08. Dealer replaced motor and regulator $588 cost. Complained to chevy in Dec '08, they said small plastic part had failed but since it was past warranty and I waited 2 months to complain, there was nothing they would do. They also said it was a known, infrequent problem and they were redesigning the mechanism.
When the consumer attempted to accelerate from a stop, the vehicle hesitated intermittently. The vehicle needed a new alternator, radio system (cd would over heat).
