I have a question about the Ford Intermittant wiper switch. If I want to change my truck from regular High & Low Wipers to the three speed with the delay, what has to be changed? Is it just the switch? or do I have to replace the wiper motor too? Let me know. Thanks.
You will have to change the switch and a small electrical circuit housed in a plastic box which the wiper switch is plugged into. I did this conversion on my 79 F250 and it just plugs in to your existing wiring and uses your wiper motor you already have. You can usually find the switch and box on ebay. I believe I might have seen Mil1ion say he had one of these for sale once or twice.
Here is another question. I have a 68 and a 73 part truck. Will the intermittent switch go into my 68 or do I have to take the system out of the 73 and put it into the 68?
