Steering column trim panels also covered in this tech article

At the steering column are the controls for options on your Volvo V70. You can operate the turn signals, wipers and cruise control via the steering wheel switches. The switches are all mounted to the steering column and covered by trim panels. At the center of the steering wheel in the horn pad and airbag. In order for the horn and airbag to function while the steering wheel is rotated, an electrical connection has to be made. These connections are made via a rotating ribbon cable called the clock spring. The clock spring rotates with the steering wheel winding and unwinding a ribbon cable to maintain the electrical circuits.

When the clock spring fails, it usually leaves a fault code for the driver airbag. If you suspect your clock spring is responsible for a fault code, especially an airbag fault code, have it professionally diagnosed. See our tech article on clock spring replacing.

In this tech article, I will go over how to replace the clock spring on Volvo V70 base models.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

Release the steering wheel position adjuster. Then move the steering wheel all the way forward and as low as it will go. Then, remove the steering wheel. See our tech article on steering wheel removing.

Then remove the lower cover down at an angle. If you're replacing only the electronic switch, the remaining steering column items can remain installed. If you're replacing the lock cylinder, remove the clock spring (green arrow) and the steering column switches (red arrows). See our tech article on the related items if needed.

Working at the bottom of the clock spring, disconnect the electrical connector (red arrow) by squeezing the release tabs and pulling it straight off.

Align the clock spring tab with the hole located at about the One O'clock position.
Figure 8

Align the clock spring tab with the hole located at about the One O'clock position. Use a small drill bit or a piece of solder (green arrow) to lock the clock spring in place. Working at the top of the clock spring, remove the final T25 Torx fastener (red arrow).

Pull the clock spring down and off the steering column.

Pull the clock spring down and off the steering column. Then disconnect the final electrical connector by pulling it straight off (green arrow).

To install a new clock spring, connect the rear electrical connector.
Figure 10

To install a new clock spring, connect the rear electrical connector. Then, slide it onto the steering column and install and tighten the fasteners. Install the trim pieces in the reverse order of removal. Then install the steering wheel and airbag. Check the operation of the switches and the fit of the trim panel. This photo shows the clock spring tab aligned with the hole (green arrow) located at about the one o'clock position. Note the piece of solder (red arrow) locking it into place.
