The MOST important step of the mirror removal/replacement process was skipped . MAKE SURE IT IS RE-SEALED WHEN YOU RE-INSTALL !! Learn from MY first-hand experience (one of many problems I had with my SVT early on) . If it's not sealed , you will have gallons of water on your front floor !!
From the factory (bought my SVT new) , my driver's side mirror wasn't sealed correctly and every time it rained my mats were floating . It was a PITA to track THAT leak down . After many , many trips to the dealer & several seals & adjustments , I figured it out with a bucket & some water . I re-sealed the foam & from then on out ... NO LEAK ! Remember , it doen's take much of a "hole" to make a great big leak !
