How to Change a Clockspring in a 2002 Jeep Grand Cherokee

The clockspring provides constant electrical contact to the steering wheel-mounted module and related components. Its primary responsibility is feeding power from the battery to the air bag for emergency deployment. If the clockspring fails, it affects the air bag, horn, and cruise control, if equipped. As with any part, the clockspring may fail due to age. It is especially susceptible due to the constant rotation of the steering wheel. There are two versions of clocksprings. If you have cruise control, you need the three-wire version. Otherwise, buy the two-wire model.
