NZ Mercury has the 41 American Dash set up. The fitted wiper motor was the type which had a wire pull for on off, not the correct one but it would park the wipers at outside of screen.

Fitted the correct wiper switch which has the variable speed adjustment and a NOS 1941 Trico Wiper Motor SSR1-1. This motor works really well.
However now the wipers now park in the centre by screen division. i saw this on another post and this is how it should be? Dont seem to be able to correct via repostioning of wiper arms. Its the small air line off the wiper switch that goes to the "park valve" on the wiper motor. Is it possible this can be corrected, as without this park valve the wipers would stop when switch is pushed in. Dont really want to mess with this motor as its running great except for the centre park position of wiper arms.

This is more or less the last of the little run items i have attended to since purchasing this car.Been driving it and working through the list of things to do. The ride with this model is cetainly a smoother different ride to the 39 coupe and 38 PU guess the improvements over those years.
