A motor vehicle’s steering column contains a variety of electrical wires and connections. The operation of the windscreen wipers and the vehicle’s lights are almost always based in switches on either side of the steering column. In many vehicles, the horn, cruise control, audio system controls and even the gear shift are located in the steering column.
Because the steering column contains so many mechanical and electrical parts it needs to be protected and the way in which this protection is achieved is by way of the steering column cowling. In simple terms, the steering column cowling is a cover, typically made from plastic, which is used to enclose the contents of the steering column. Not only does this protect the electrical parts from the risk of damp and short circuits it also keeps moisture and dust away from the mechanical parts.
Most steering column cowlings come in two pieces, for ease of fitting and removal. Although a relatively cheap and straightforward component, it still plays an invaluable role in protecting the contents of the steering column and the steering assembly from the effects of damp and dirt and protects the driver from possible contact with the vehicle’s electrics. Replacement of a broken steering column cowling is relatively cheap and simple.
