    Malfunctioning rain sensor 2000 Deville

    I'm at my wits end. Had Cadillac in twice for same problem. If I turn wipers on then off, periodically they will wipe even with the turn signal wiper switch in the off position. The same thing happens after I run it through the car wash and the wipers were never turned on. They've replaced the wiper motor twice and the same thing still happens. They're fine after the ignition has been off for awhile but as soon as I use them just once they'll wipe fast, slow and intermittently periodically with the switch in the off position. Can you disconnect the rain sensor as I suspect this is the problem.

    If the wipers are working even when it's "OFF", I'd suspect the multifunction switch (turn signal lever).

    NEVER post your e-mail in a worldwide public forum. You may receive far, far more than you bargained for. Log in here once in a while to see if someone has responded. If the "Notifications" tab ^^^ has changed color, you have either a PM or some other CF contact info.

    Yes, just remove the sensor cover behind the rear view mirror and unplug it. That's what I did with mine as I never cared for it anyway.
