So I just purchased my first car and it just so happened to be a 94 mustang gt! It's an older car so of course it has some things to be fixed here and there. One of them is the windshield wipers. For some reason they turn on when the car is turned on and off. They also work when you press wiper button, but they don't work when you try and use the normal wiper settings. I'm very new to cars so sorry if I don't quite understand.

 

replace the wiper switch
