Component Testing

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

Horn

  1. Ignition OFF, disconnect the harness connector at the horn assembly.
  2. Install a 15A fused jumper wire between the control terminal B and 12 V. Install a jumper wire between the ground terminal A and ground. Verify the horn emits a clear and even tone.
    • If the sound emitted is not clear and even, replace the horn assembly.
