wiper switch problems - dirty contacts?
 

Hey guys I have a little problem with my wiper switch (S4) where it gets kind of stock on the Mist setting. That is, when I use the Mist setting they just keep going and going and I have to cycle between "I" and "Int" and wait for them to stop then I can safely set it to "Off."

Could this be a problem with the relays in the switch or the contact points of the knob?

I've read Icemark's DIY on his website but that focused on replacement of the relays primarily.

Bad 2nd relay. PM me.
