Replacing power mirrors on 2003 Ford Focus SE
There are a number of sites with information on how to replace power mirrors on the 2003 Ford Focus. I won't repeat that information, but I have some tips which will help make the installation go smoothly:
1. The power mirrors are held in place by a large bolt accessible through a hole in the door panel and a Torx screw accessible from the inside of the door. You don't have to remove the door panels to replace the mirrors. Before you do anything else, carefully unscrew the Torx screw with a No. 20 Torx screwdriver, and put the screw and washer safely into a pocket for later use.
2. Be very careful when you remove the plastic triangular interior trim pieces which cover the power mirror electrical connections. They are held in place by two metal clips which are razor sharp. There's also a plastic clip which isn't sharp. Grasp the trim piece on the side facing the window at the top of it and pull it toward you. Be aware of the metal clips when you're working around them. The knob on the driver's side trim piece that adjusts the mirrors is attached to the trim piece, so you don't have to remove the knob. Remove the driver's side trim piece in the same way as the passenger side trim piece. However, unlike the passenger side trim piece, because of an electrical connection the driver's side trim piece can't be completely removed, but it can be pushed out of the way while you're working.
3. After you unbolt the old mirror using a socket wrench and extension with a 10mm socket, while your socket wrench is keeping pressure on the bolt, take a large paper-clip and push it onto the threads of the bolt. A small spring-type clamp will also work. That will prevent the bolt from falling into the interior of the door panel. You remove the paper-clip or clamp when you have the socket wrench in place to screw the bolt into the new mirror.
4. When you're re-attaching the triangular interior mirror trim pieces, use only hand pressure. Do not tap the pieces in with a hammer or rubber mallet because it will crack the plastic. If you look down from above the trim pieces, you can see how to put them back into place.
These tips should help make power mirror installation hassle free. The installation can be done by yourself, but it helps to have someone hold the new mirror for you when you screw the bolt back in. Under normal conditions, installation of a new power mirror should take about 30 to 60 minutes. Since car repair shops can charge as much as $100.00 labor per mirror, there's an incentive to do it yourself.
