One problem related to windshield wiper/washer has been reported for the 2004 Chevrolet Avalanche. The most recently reported issues are listed below.
Nuts retaining wiper arms to shaft loosened on both driver and passenger side causing wipers to not move. I tightened the nuts as a temporary fix and will replace with lock nuts.
