Rear Door details

The only required tools are 8mm hex socket and a large flat screwdriver or other prying tool, preferably of plastic or wood to avoid paint damage. Also a 9mm hex socket is required to remove the outside door protection strip.

Removal of outside protection strip

Open door and unscrew black plastic nut using a 9mm hex socket. Carefully pry the protection strip slightly outwards and push it forward to release it from the front clip. Assembly is reverse. Take care not to overtighten nut.

Removal of inside door trim

Pry out the wood trims from each side of the door using a large screwdriver or prying tool. Two clips holds the rear one, and one the front one. After uncliping simply draw them out.

Unscrew the two 8mm hex bolts on each side of the doorhandle.

Now only 12 green plastic clips hold the trim onto the door. Carefully unclip these using the same prying tool. See photo for locations.

Afterwords the trim is held in place by 6 metal clips under the window cromelist. Lift up and unhook from these clips. Now the trim is loose and you will want to unhook the doorhandle wire from the handle (blue wire with a hook), and remove the 3 electrical connectors, the windowswitch, footwell light (black plug) and ashtray light (white plug).

Assembly is reverse. Take care to connect the electrical connectors. You may want to grease them up for continued uninterupted operation. Also don´t forget the doorhandle wire, and the lock-knob rod.

Push the trim onto the 6 metalclips first, and then carefully align the green plastic tabs. Replace any broken tabs with new ones. These are important for continued noise-insulation. Bolt back in both 8mm hex bolts, and clip on the woodtrims. Check operation of all blubs and switches.
