Take the wind shield wiper arms off by removing the hold down nuts and rocking wipers back and forth. Then remove the cowl panel or air inlet panel from there remove the whole wiper module. The park for the wipers is in the motor assembly. that is what will need to be replace.
shut your wipers off in the park position, mark them on them on the shafts were they are, then just move the linkage to were they are down, I can't remember how many splines are on the motor but if you get it close you can set your wiper arms to where you need them. and I would try them before you put the cowl back on.
Turn the key on, then turn the wipers on.
Turn the wipers off but do not turn the key off.
The wipers will park, but the blades will not be down near the cowl like they should be.
Loosen the nut that holds the wiper arm to the stub that comes up through the body. You don't have to take the nut all the way off, just loosen it.
Wiggle and rock the wiper arm until it comes loose from the stub.
Rotate the wiper arm until it is at the park position.
Do the same with the other arm.
Turn the wipers back on and hit the washers. Then turn off the wipers and check the park position of the blades. You might have to adjust one or both just a bit to get it in the correct position, but they will be close if not spot on.
Did you ever remove the wiper arms from the stubs?
I think I understand what is happening. But I need to know if this is going to take two adjustments or just one. If the wiper blades were taken off the stubs, it will take two adjustments. If they haven't been removed, it will only take one adjustment.
Disconnect the linkage from the motor and take off the wiper blades. Turn the motor on and off with the wiper switch.
This will put the motor in the park position. Put the linkage back onto the motor. The crank will be either pointing to the extreme left or right, looking at it from the front. I think it's pointing toward the drivers side, but I don't have a picture so I can't recall. But with the motor parked, the blade stubs will be at the bottom of their sweep, which the extreme end of their travel.
This should synchronize the linkage to the motor. Test it by turning on and off the motor. Then with the wiper motor parked, attach the wiper blades so that the blades are parked.
You may be off one spline because there is no load when the wiper motor parks, but this is easy to adjust once you get close.
