Test K: Radio Interference

WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

  1. Verify Radio Interference

    Start engine and let idle. Tune radio to station where interference is present. Turn ignition switch to LOCK position. Disconnect upper generator 3-pin connector. Start engine and let idle. If interference is not still present, install a new upper generator. See GENERATOR (UPPER)  under REMOVAL & INSTALLATION. If interference is still present, go to next step.
  2. Verify There Is Radio Interference

    Turn ignition switch to LOCK position. Connect upper generator connector. Disconnect lower generator 3-pin connector. Start engine and let idle. If interference is not still present, install a new lower generator. See GENERATOR (LOWER)  under REMOVAL & INSTALLATION. If interference is still present, repair radio concern.
