Frequently Asked Questions

Can I replace just the cruise control switch?

On many vehicles, the steering wheel switches are replaceable individually or as a module without replacing the entire steering wheel. The switch panel usually pops out of the wheel.

Is the cruise control switch part of the clock spring?

No, the switch is a separate component mounted on the steering wheel. However, the signal from the switch passes through the clock spring to reach the cruise control module.

Why do steering wheel switches wear out?

The buttons are pressed thousands of times over the life of the vehicle. The contact pads inside the switches can wear thin, corrode, or crack, leading to intermittent or no function.
