There are three separate components to the exterior mirrors on your Mercedes W203: the housing, the mirror and the complete assembly. If you live in a large city there is a very good chance that someone will damage a part of, if not the whole mirror assembly. This article will guide you through replacing all three.

First is the mirror housing. You will need to remove the housing to perform work on the assembly and while you can replace the mirror with the housing on it is a lot easier with the housing off.

Begin by bending the mirror in towards the door (it pivots on a hinge and spring). The spring can be tight so you may need a friend to hold it in place while removing the housing.

While holding the housing folded inward you will need to insert a flat head screw driver between the inside of the housing and the small clip that holds it in place. Pry the clip in towards the center of the mirror and it will release the housing from the mechanism. You can now just slip the housing of the mechanism.

With the housing off you can remove the mirror. There is a small metal retaining wire that holds the mirror to the assembly. Unclip the wire and gently pull the mirror from the housing. There are two wires that run to the mirror, these wires heat the mirror and are very delicate. Use care when replacing them.

There are three T20 Torx screws that hold the assembly on the door. You do not need to bend the assembly towards the car to remove it if you have a long handled Torx driver as the housing is designed around access to these screws.

Remove the assembly from the door and separate the wiring connection. Push the clip in and slide the grey bar down, this will push the harness from the housing.

If your mirror has been damaged to the point where you need to replace the wiring harness you will first need to remove the door panel. Please see our project on removing your front door panel. To replace the harness unplug the two connections going into the wiring module in the door and pass the harness through the cutout in the door.

Mrclicky Comments: My folding door mirror sticks is there ant where you can spray some WD40. On the gears?

Nicki Comments: I am not able to slide the housing back. It does slide back but it comes off easily any idea how I can click it back in?

  Followup from the Pelican Staff: There are clips that hold the mirror cover on. See attached photo. If the clip (red arrow) is bent or worn, the cover will not stay on. Also check that the cover isn't damaged where it makes contact with clip. - Nick at Pelican Parts
kcstohr Comments: the mirror is turning into a bronze color i have the mirror and just want to replace that part. I have a 1998 clk320 mercedes. the mirror on my car are different than the ones you show in your instructions.

  Followup from the Pelican Staff: The mirror glass should pop off. Cover the mirror with tape, then lever it off with a plastic prying tool. Once free, detach the wiring and install the new mirror glass. - Nick at Pelican Parts
