Cars Specification

1. Open the hood of your Mercedes and locate the mass air flow (MAF) sensor, mostly found between the air cleaner box and the air intake pipe of more modernized engines.
2. Unfasten all of the clamps that hold the air filter box to the intake hose and disconnect completely. Remove the air filter inside and thoroughly clean this area of any dirt that may have built-up over the extensive use of your Mercedes. This step is not imperative to removing and replacing the MAF sensor, but it will certainly help improve the functionality of the new sensor once installed. Replace the air filter if necessary, but leave the air box disconnected at this time.
3. Use the necessary socket to remove the bolt that holds the clamp of the air intake pipe. Remove this piece to free the intake pipe.
4. Pinch both sides of the MAF sensor and wiggle free until you have completely removed this part from the engine. Be patient, as this may take a few moments of your time to loosen.
5. Compare the old MAF sensor that you just removed with its replacement counterpart. Make sure both sensors match identically and replace the new MAF sensor exactly as the new one was removed. It should slide on very easily, with little wiggling to set into place.
6. Reconnect all of the parts that were removed to access the MAF sensor and clean the air filter box. Make sure all bolts are tightened properly to hold the intended clamps together, ensuring that the air intake tube and air filter box both are set exactly as they were before removal and installation of the MAF sensor.

1. Pull the wiper arm away from the windshield until it locks in a vertical position.
2. Clear away any debris with a nylon-bristled brush. If this does not fix the problem, you may need to replace the motor or the wiper assembly. If the wiper arms are bent, replace the arms. If the blades are worn, replace them. If the wipers hesitate while on or the motor seems weak, replace the motor.
3. Press down on the release tab on the top of the wiper blade assembly and pull the wiper off of the wiper arm. Slide the new wiper blade into the wiper arm lock. Installation is the reverse of removal.
4. Replace the wiper arm. To do this, remove the nut at the base of the wiper arm with a socket wrench and pull out the wiper arm motor. Installation is the reverse of removal.
5. Replace the wiper motor. To do this, open the hood and unplug the wiper motor electrical leads (the wiper motor is on the firewall). Unbolt the wiper motor from the firewall and slide the old motor off of the firewall. Install the new motor. Installation is the reverse of removal.

1. Open the hood. Detach the negative battery terminal with a wrench.
2. Locate the cowl trim around the edges of the instrument cluster. Use a Phillips screwdriver to remove the two screws that secure the cowl. Lift the cowl away from the instrument cluster.
3. Remove the three mounting screws attached to the cluster. Unhook the electrical connectors from the back of the cluster. Slide the cluster out of the dash and place it on a flat work surface.
4. Unscrew the broken bulbs in a counterclockwise direction. Discard the broken bulbs. Install the new bulbs by turning them in the opposite direction.
5. To reinstall the cluster or install a new one, simply follow the removal steps in reverse. Reattach the negative battery cable and turn on the engine to test the indicator bulbs in the instrument cluster.
