Preparations:
1. Park your vehicle in a safe and well-lit area, preferably on a level surface.
2. Turn off the engine and allow it to cool down if the engine has been running.
3. Engage the parking brake to ensure that the vehicle remains stationary while you work.
4. Locate the necessary tools, such as a screwdriver or a socket wrench, depending on the specific type of mirror assembly.
Removing the Old Turn Signal:
1. Locate the right side mirror on your C240. The turn signal is usually integrated into the mirror housing.

5. Unscrew or unbolt the turn signal assembly from the mirror housing.
Installing the New Turn Signal:
1. Take the new turn signal assembly and compare it to the old one to ensure that it is a suitable replacement.
2. Reconnect the wiring harness to the new turn signal assembly. Make sure that the connection is secure.
3. Position the new turn signal assembly onto the mirror housing and align it correctly.
4. Secure the turn signal assembly by replacing the screws or bolts that were removed earlier.
5. Reconnect the battery, if disconnected, and test the turn signal functionality by turning on the ignition.
Verifying Functionality:
1. Turn on the right turn signal and check if it is working correctly.
2. Check if the turn signal light is visible from outside the vehicle.
Clean Up:
1. Once the turn signal is functioning properly, dispose of the old turn signal assembly and any removed parts responsibly.
2. Close the hood and clean up any tools used during the replacement process.
