Turn signal switches have been required to be on the steering column since the late 60's. Many manufacturers thought that having all the switches within the driver's reach would make driving safer by keeping the driver's hands on the wheel. In the case of our w211 chassis, this includes the cruise control switch, which is mounted at the 12 o'clock position. The steering wheel adjustment switch is mounted at the 7 o'clock position. The turn signal switch is mounted at the 9 o'clock position. With the addition of ABS, ASC and ESP a steering angle sensor has been added to the components found in the steering column. This sensor tells the ESP module what direction the steering wheel is pointing. With this sensor, the ESP module knows where the driver wants to go. In situations with limited traction, the ESP module can limit throttle opening, have the ABS unit apply the brakes to spinning wheels and control the suspension stiffness. The steering column adjustment switch allows the driver to find a comfortable position by adjusting the steering column up and down as well as forward and rearward. In this tech article we will go over the steps to replace all the switches in your steering column.
In order to remove your steering wheel switches you will have to remove the steering wheel first. See our tech article on Steering Wheel Removal.
