I have a 1975 F250, and the windshield wiper switch only works on the 'high' setting. My truck does not have intermittent wipers. I was looking in the LMC catalog, and they have two switches available - one for models with intermittent wipers, and one for models without.

ASSuming the switch is my problem - does anyone know if you can install the switch for intermittent wipers to a truck that did not come from the factory with intermittent wipers, and reap all the benefits of delayed wiper action? Or are there other parts involved in the intermittent wiper setup?

Thank you in advance -

Glenn
