WIPER BLADE TRAVEL ADJUSTMENT
Posted by Rob Pittman on Sat Oct 6, 2007:
I seem to remember this coming up on the old list, but I can't find my archive of the old messages.
The problem is that my wipers are traveling too far on the upstroke, yet they appear to park in the correct position. At times the driver's side wiper will come completely off the windshield and onto the roof pillar. Is there any way to adjust the amount of travel? Is the linkage worn out? Is this a sign the wiper motor is about to go?

The wiper arm attaches to the linkage with a set of splines. You can pull the arms off and shift them a few splines to reduce the overtravel. If the arms haven't been removed in a while, it may be that something is worn out. To remove the arm, there is a tab that must be pulled out. Lift the blade off the glass a few inches, and pull on the tab with a pair of pliers and you should be able to lift the entire arm off of the splines.
