Relays are a very common source of failure in the 911. There are several different relays used on the 911. All are subject to failure after many years of service. Before suspecting your wiring or your components, be sure to check your relays. It is wise to have at least some spares on hand so that you can check proper operation of the ones that are installed in your car.
