    Q:
    How do you ensure the proper installation and alignment of wiper arms on Chevrolet Caprice? Posted by Customer
    A:
    Ensure that the wiper arms are in the self-parked position with the motor switched off in low speed mode. Carefully note the position of the wiper arm in relation to the windshield lower reveal molding, using tape to mark the exact location on the glass. With a suitable hooked tool or small screwdriver, pull aside the small spring tang that holds the wiper arm to the splined transmission shaft while simultaneously pulling the arm from the shaft, prying up the cover plate if necessary. For installation, reverse the removal process but do not push the arm fully onto the shaft until the alignment has been checked; if needed, the arm can be pulled off and turned through one or two serrations of the shaft to correct the alignment without pulling aside the spring tang. Finally, press the arm fully onto its shaft, wet the windshield glass, and operate the motor on low speed to ensure the arc of travel is correct.
