Cause: The plastic windshield water run off duct may not be properly sealed or fastened to the cowl locating directly above the alternator. This can lead to water running down the windshield to be directed onto the alternator. The water can freeze inside the alternator resulting in intermittent operation or complete failure of the alternator. Correction: If the alternator has been damaged, replace it. Reseal the windshield water runoff duct, ensure that it is secured and sealed against the cowl. Pay careful attention that the duct is properly sealed at the 3 studs where it attaches to the cowl. Revision 20090521 expanded the applicable years and models to include the 2002 Express and Savana vans.
