My '81 DL wagon does not have the intermittent rear wiper feature that the GL models had. In the Seattle area, it would be great to have that with all the mist we have. The rear wiper switch on the wiper stalk has both the on position and the intermittent position, but only the on position works the wiper. What would be involved in upgrading to the intermittent feature? It seems that the motor would not need to be changed. Is it just a relay that would need to be added? Any one done this upgrade before?
