Where is the horn relay on a 2012 Lexus RX 350?
As the owner of Kevin's Autos auto service, I've had years of experience working on a wide range of vehicle makes and models, including the 2012 Lexus RX 350. In this article, I'll provide a detailed guide on locating the horn relay in this particular vehicle.
Finding the Horn Relay
The horn relay on a 2012 Lexus RX 350 is typically located in the engine compartment fuse box. To access the fuse box, follow these steps:
- Open the hood of the vehicle and locate the fuse box, which is usually situated on the driver's side of the engine compartment.
- Refer to the fuse box diagram, which is usually located on the underside of the fuse box cover or in the owner's manual, to identify the horn relay.
- The horn relay is often labeled as "HORN" or something similar on the fuse box diagram.
Once you've identified the location of the horn relay, you can visually inspect it to ensure it's functioning properly. If the horn is not working, the horn relay may need to be replaced.
Replacing the Horn Relay
If the horn relay needs to be replaced, follow these steps:
- Locate the fuse box and identify the horn relay.
- Carefully remove the relay from the fuse box, taking note of its orientation to ensure the replacement is installed correctly.
- Insert the new horn relay into the fuse box, making sure it's securely in place.
- Close the fuse box cover and test the horn to ensure it's now functioning properly.
