Well, what a timely return by DiscoWeb. Just two weeks ago, my interior rearview mirror began leaking ugly "brownish-blackish" fluid and developed a large splotch in the center of the glass. Now, I find that I can contact Magna Donnelly and get a replacement. I called them on Monday, they asked me to send some digital photos to confirm which model mirror I need, and promised to send a replacement as soon as they get in a new shipment from Ireland, where the mirrors are manufactured. We'll see what happens.
Thanks, DiscoWeb, for making this forum available so I can find such great information so readily.
