Some customers may comment on a clicking noise that can be heard from the passenger side floor (foot) area when the brake pedal is pressed.
Some vehicles may have been produced with a relay that exhibits slightly louder operational characteristics. The amount of noise is the only concern, as the relays will function normally.
Inspect the relay for the stop lamp located on the passenger side of the vehicle, under the instrument panel and under the passenger side toe-board. The relay should have part number 12193606. Verify that the clicking noise is coming from the relay by switching the ignition to ON and have someone press on the brake pedal while listening in the passenger foot well. Verify that the relay has part number 12193606 stamped on it. If the relay has 12193606 stamped on it, do not replace the relay. Relays act as a switching device and some amount of clicking noise is normal. If the relay has a different part number, replace it with relay part number 12193606. If the noise does not originate from the relay, do not replace it.
Tip: All mechanical relays have some level of noise when operated.
