I had a shop install my side mirrors. They won't adjust even close to far enough out. Did they put them on backwards or upside down? Or is something in them broke? The first set of poctures is driver side (lhd)
There is a heavy spring the in mirror holding tension on the joint. Like shay2nak pointed out, you may have to grab the mirror housing with both hands, outside of the car, and pull away from the car as you make an adjustment. You can see the pieces on the lower right side of the picture below.
