The turn signal and wiper switches are some of the most commonly used items in your car. Over the years, and due to the plastic construction, this can result in a switch that fails, rendering the turn signals or wipers non-functional. Replacing the switches is relatively easy, although it does require removing a few items to gain access.

It is important to disconnect the battery before starting. You will need to remove the airbag, steering wheel and the instrument cluster trim surround to access the switches. Removing the airbag with the battery connected can be very dangerous. An errant voltage spike can trigger the airbag, which would certainly ruin your day. Please see our articles on Battery Replacement, Steering Wheel Removal, Airbag Replacement and Instrument Cluster Removal for more information.

It is also important to determine which switch you need for the car. Volvo lists different switches depending on which options your car has. There are two different turn signal switches, for cars with and without the trip computer. There are also two different wiper switches, for cars with and without the rain sensor in the windshield.

Shown here is the steering column on the Volvo C30 with the steering wheel removed.
Figure 1

Shown here is the steering column on the Volvo C30 with the steering wheel removed. The first step is to remove the upper steering column cover. Carefully use a small trim removal tool along the parting line on each side of the column (green arrows). You'll want to pry the lower cover ears forward.

Shown here are the locking clips on the upper cover (green arrows).
Figure 2

Shown here are the locking clips on the upper cover (green arrows). Once the clips are free, pull the cover towards you in the direction of the yellow arrow to remove the upper cover from the steering column.

Move to the underside of the steering column.
Figure 3

Move to the underside of the steering column. You'll see three access holes (green arrows). There is a T25 Torx screw in each hole. Loosen and remove each screw. This will release the lower cover from the steering column.

Pull the rubber trim piece out from the lower cover (green arrow).
