    New wiper motor. Pump will be installed but not connected
    Previous motor worked but shaft end had a lot of play. So wire and switch should be good

    Engine running
    moved switch to both run positions
    wiper shaft not turning
    multimeter 13.4v at power connection
    multimeter 3.2v at LBL wire connection
    multimeter 0v at ground connection

    Engine off
    removed black ground wire
    ws switch off
    multimeter shows no continuity between ground wire end and at switch ground point
    Move switch to both run positions and multimeter shows continuity

    Is a replacement wiper motor called for?
