so according to that TSB it requires replacement door modules and reprograming of new software... HUm..... I know thats for Lincoln but ill ask my dealer about that.Its a ford problem, the expeditions and explorers do it as well, the colder it is the worse it gets. As you enter the car with a memory saved fob or memory position set the car is positioning your mirrors. Basically the computer loses track of where the mirror is and is trying to move it down or up at the end of its travel.
A few suggestions are that the first step the computer does is move the mirror a tiny amount in every direction to check it and assumes the increased resistance means its at the end of its travel so thinks it needs to move a lot but in fact the grease has thickened or there is ice behind the mirror.
Another is that the computer loses track for some reason of where the mirror is positioned after last shutdown and is now trying to move it past its max but that never explained to me why winter made it worse.
To quickly fix it temporarily use your mirror adjustment to reposition the mirror somewhere near where you want it to be and hit the memory button again, 9 times out of 10 it will reset properly to your preferred position.
There is a TSB somewhere on this but basically all the TSB does it tell the computer do it more slowly. :(
I know I have also had issue with ice build up behind the mirror where paring in a heated garage overnight has solved the problem for a week or so.
