Frequently Asked Questions
Is the heated steering wheel connected through the clock spring?
Yes. The electrical connection for the heated steering wheel runs through the clock spring, the same component that carries the airbag and horn connections.
Can the steering wheel heating element be replaced?
In most cases, the steering wheel must be replaced as a unit because the heating element is embedded in the wheel. This makes it an expensive repair.
Why is my heated steering wheel only warm on part of the rim?
The heating element is a thin wire that wraps around the steering wheel rim. If part of the wire breaks, only the sections before the break will heat up.
