As documented here
, a couple/few years back I installed a JDM rear wiper setup on my sedan. The wiring was all scavenged from a Legacy wagon, so (AFAIK) it's all the same as a wagon's rear wiper.
If I turn the wiper on, it goes continuously - there is no interval at all between sweeps. I've never had a wagon myself, but for whatever reason my impression was that the wagon rear wiper does
have an interval, that it only sweeps maybe once every 8 or 10 seconds. Am I wrong on that?
