ADJUSTMENT



The only adjustment for the wiper arms is to remove an arm from the transmission shaft, rotate the arm the required distance and direction and then install the arm back in position so it is in line with the blackout line on the glass. The wiper motor must be in the park position.

The correct blade-out wipe position on the driver's side is 1 1 / 32 in. (28mm) for 1982-85 models and 11 / 16 in. (18mm) for 1986-96 models, from the tip of the blade to the left windshield pillar molding. The correct blade-down wipe position on the passenger side of the car is in line with the blackout line at the bottom of the glass.
