How do you replace a manual drivers side mirror on a 1999 Saturn SL2?
If it is like the 99 SL then open the door, remove the black cover in the corner of the window on the inside. Remove the 3 nuts using 10mm socket, remove black cover, or mirror from the outside. Place new mirror from the outside, put nuts back on the 3 posts or bolts from the inside, replace black cover by firmly pushing back on and you are done. Hope this helps...good luck
