If adjustment is needed, follow these steps: (a) Remove the right wiper arm. (b) Open the small door to access the wiper linkage. (c) Loosen, but don't remove, the transmission linkage adjustment nuts. (d) Rotate the left arm and blade assembly just below the blade stops. (e) For 1990 vehicles, tighten the transmission adjustment screws to 64 inch lbs. (f) For 1991 vehicles, tighten the transmission linkage adjustment nuts to 44 inch lbs. (g) For 1992-up vehicles, tighten the transmission linkage adjustment nuts to 71 inch lbs.
