The service manual shows how to replace the direction switch.

Very easy job to do, the CID plastic housing parts are a bit tight to clip back together on reassembly.

Watch the wiring loom as you lift of the top housing part of the CID as its clipped inside to the housing, gently lift the housing up, unclip the loom then you can get inside the CID to replace the switch.

The little torx screws that secure the switch are easier with a magnetic bit / torx screwdriver.
