    I removed the entire wiper assembly to replace the sparkplugs, but when I put it back on, the passenger wiper was like an inch resting on the plastic, not the glass. I can adjust the driver's wiper unscrewing a nut, but on the passenger's there is no way to do that.
    Any suggestions?

    Is it not on a spline shaft, like all my cars where I've removed and re-installed wipers. To reduce wiper icing in certain conditions on prior vehicles, I've pulled the wiper and reset it one spline tooth higher to get it up on glass heated by the defroster.

    The passenger wiper is attached to two pivots, not just one.

    Remove both nuts, and lift the wiper links straight off the pivots at both points. Do not twist while lifting; the splines are very fine and easy to mash flat.

    After removing the wiper, not everyone does this, but Toyota recommends scrubbing the splines (vertically, along the splines, not across them) with a brass bristle brush, doing this both for the shafts sticking up from the cowl and the holes in the wiper links.

    With the blade removed, cycle the wipers once to make sure they have stopped in the parked position.

    Now reattach both links of the passenger blade, to both pivot points. Hold the blade so that its tip will be at the small round dot in the windshield that indicates the blade's parked position, and lower both links straight down onto the pivot points. Do not risk stripping the splines by moving the blade.

    Then hold it in the proper position and tighten the nuts to the proper torque.
