1965 My dad let drive his 1939 LaSalle. It was raining that day and the windshield wipers didn't work. The inspector got in the car and we took off. I was afraid if I turned on the wiper and it didn't work I would have to come back and take the test again. Finally he asked me if I was going to turn on the windshield wipers so I reluctantly reached down and turned on the knob. Much to my surprise they started working and they did so all through the driving test. On the way home I tried to turn them on again and they didn't work. In fact they never worked again. I guess it was meant to be.
