Mercedes-Benz E-Class W124 CKD Wiper (1993-1995): A Comprehensive Guide

The Mercedes-Benz E-Class W124 is a series of mid-size luxury cars produced from 1984 to 1995. In 1993, Mercedes-Benz Indonesia (MBI) commenced the local assembly of the W124 E-Class, known as the "CKD" (Completely Knocked Down) model. These locally assembled vehicles played a significant role in expanding the E-Class's market reach and affordability in Indonesia.

Wiper System

The wiper system on the W124 CKD E-Class comprises several key components, including the wiper motor, wiper arms, wiper blades, and a wiper relay. The wiper motor, located in the engine compartment, provides the power to drive the wiper arms back and forth across the windshield. The wiper arms, attached to the motor, hold the wiper blades and move them in a sweeping motion. The wiper blades, made of rubber material, sweep away rain, snow, and other debris from the windshield.

Operation

The wiper system in the W124 CKD E-Class can be operated manually or automatically. The manual operation is controlled by a stalk on the steering column. By flicking the stalk up or down, the driver can activate the front or rear wipers, respectively. The automatic operation utilizes a rain sensor mounted on the windshield. When rain is detected, the sensor triggers the wipers to operate at varying speeds depending on the intensity of the rain.

Wiper Relay

The wiper relay is an essential component in the wiper system, acting as an electrical switch that controls the power supply to the wiper motor. When the wiper switch is activated, the relay allows electrical current to flow into the motor, causing it to operate. The relay also manages the intermittent wiping function, allowing the wipers to sweep at regular intervals.

Maintenance

Regular maintenance of the wiper system is crucial to ensure optimal performance and longevity. Here are some important maintenance practices:

- Wiper Blades: Replace the wiper blades every 6-12 months or sooner if they exhibit signs of wear, such as streaking or chattering.

- Wiper Arms: Inspect the wiper arms for any damage or corrosion. Ensure they are firmly attached to the wiper motor and move smoothly across the windshield.

- Wiper Relay: Listen for any clicking sounds when the wipers are operated. If a clicking sound is present, it may indicate a faulty relay.

- Wiper Motor: Have the wiper motor inspected by a qualified mechanic if it fails to operate or exhibits abnormal noises.

Replacement

In the event that the wiper motor, wiper arms, wiper relay, or other components fail, they may need to be replaced. Replacement parts are available from Mercedes-Benz dealerships or authorized parts suppliers. It is recommended to consult a qualified mechanic for any replacement or repair work.

The wiper system on the Mercedes-Benz E-Class W124 CKD is a vital safety feature that ensures clear visibility in adverse weather conditions. By understanding the operation, maintenance, and replacement procedures, owners can keep their wiper system functioning optimally and ensure safe and enjoyable driving experiences.
