Why do the windshield wipers on my 1999 Mercury Sable LS come on by themselves?
your wiper switch at the end of your turn signal is bad. Mercury Sables do not have rain sensor wipers its a bad switch.
I will give you the proper answer no Bull.I am a ford mechanic for over 25 years.Your transmission range sensor is shorting out.sending a signal to the gem module, that turning on your wipers.Ford had a SSM message for this concern.On some vehicle also turned radio on and off
Some vehicles are equipped with rain sensors. This will automatically turn on the wipers if there is rain. If the wiper come on when there is no rain or just randomly. Perhaps you should get it serviced it could be a mechanical problem or an electric problem.
