How to Replace the Horn on a Mercedes-Benz?

[BraxtonAnn]

Open the engine hood and use a T25 to remove the four Torx screws on the front grille. Insert both hands into the two elongated holes at the lowest point on either side of the emblem, wiggle and pull outward. The first removal might be tight, requiring some force to detach it. Then start the vehicle, turn the steering wheel fully to the left to facilitate the removal of the T25 Torx screws inside the fender liner. There are four T25 screws on the vertical surface. After removing the left and right bumper corners, move to the front of the car to locate the gaps on either side of the front bumper. Hook your fingers and pull towards your body. At this point, the front bumper will lower, allowing you to remove the headlight. After removing the headlight, detach the fixing screws on the rear side. The screws can be removed using either a T30 or a 10mm T-socket, with the 10mm T-socket being more convenient. You can then proceed to replace the horn.
