1984 - 1996 Corvette: Windshield Wiper Adjustment

From Jerry Watts, retired Engineer at the GM Corvette Action Center in Bowling Green, KY:

If you drive your Corvettes in the rain, you may noticed that the wipers need an adjustment. This problem can be fixed with a ratchet, a 10mm socket, and a small screwdriver.

At the bottom edge of the windshield, driver’s side, is a black screen with a small pop-off screen about 1" x 2.5" towards the inside edge. Find its two solid black spots and gently push in and up with the screwdriver to remove it.

On each wiper arm you will see two 10mm nuts. To make the adjustment, dampen the windshield and turn the wipers on just long enough to get them to where you can move them up or down, then loosen the nuts with the 10mm socket. On the driver’s side, the wiper should come up to, but not into, the blackout area along the windshield’s edge, on the passenger side, about two inches from the molding and below hood level in the rest position.
