How to Rebuild a Mercedes

1. Pop open the hood of your instrument cluster. Remove the bolt on the negative terminal clamp with a socket wrench. Lift the negative cable away from the terminal.
2. Enter your vehicle and use a Phillips screwdriver to remove the screws which fix the cowl trim around the outside of the instrument cluster. Use your hands to pull the trim away from the dash and place to one side for reattachment later.
3. Locate and then remove the four screws which fix the instrument cluster into the dash. Use your hands to unhook the electrical connector attached to the rear of the cluster. Lift the instrument cluster from the dash and place on your work area.
4. Turn the bulbs in a counterclockwise direction with your hand until they come free from the cluster. Discard the broken bulbs in the trash. Insert the new bulbs in the cluster and attach by turning in a clockwise direction.
5. Reattach the electrical connector to the rear of the cluster. Slide the cluster back in to the dash. Connect the four screws in to the cluster to fix the cluster securely to the dash. Place the cowl trim over the instrument cluster and secure back in place. Lift the negative cable back on the battery terminal and secure in place with the clamp.
