Windshield wipers come on by themselves. Appears to do it more often when turn signal is used. Comes on sometimes when just riding down the street.

    I know..this is a strange problem. There is a wiper switch module which has probably gone bad on your system. Common problem on the '99 Merc. Sable.

    I have found that when your car is out or almost out of the windshield wiper fluid it will do this. What I have done is just add some more and it will stop doing it until it needs it again.

    Have the same problem(2005 GMC Sierra). Replaced the master control stick for $223(part cost). It did not fix the problem. i'd like to know more about this "wiper control module" mentioned earlier. Any thoughts on this?
