The windshield wiper switch or relay on my 84 Berlinetta doesn't work very well. The wiper will come on when the wiper, mist or delay button is pressed, but is very difficult to turn off. Often I have to stop the car, turn off the ignition, turn on the ignition and immediately press the off button to stop the wipers. I have replaced the right pod a couple of times, but it makes no difference. Anyone have an idea how to track down this problem? Thanks for your comments.
