Lexus RX350 Horn
Lexus RX350 Horn is the main audible safety signal that notifies the driver about the presence of the SUV immediately in front of other traffic and pedestrians. Throughout the history of the RX350 line, the Horn has maintained the same objective, and the sound is either a crisp beep or a honk that slices through the noise on the road to allow other road users to respond swiftly. Older models of RX350 sounded more like older cars with a deeper honk, whereas newer models have a sharper electronically driven beep that produces a similar sound but with less power draw since the sound is produced by a vibrating diaphragm triggered by a steering-wheel button. Lexus has twin Horn units in the front to expand the sound field and enhance reliability in case of failure of one side. The Horn assembly is also sealed against moisture, which strengthens the Lexus safety philosophy. This longevity of Horns keeps costs low. All other operations are easy; drivers press a pad and the Horn talks immediately, and it is a design decision Lexus has adhered to ensure that all owners of the RX350 can rely on having a quick audible alert when danger occurs.

Lexus RX350 Horn Parts Questions & Experts Answers
- Q: How to check and replace the horn on Lexus RX350?A:As a preliminary to electrical diagnosis, always take a look at the fuses. First remove the horn's electrical connection. To check horn, connect battery voltage to the horn terminal with the jumper wire, if the horn does not beep replaced with the new one. If, however, it does sound check for voltage at the terminal whenever the horn button is pressed. If you get a voltage at the terminal then look for a bad ground in the electrical connection of the horn. But if you find no voltage at the horn, check the Relay. If the relay is working then measure voltage in the power and control circuits of the relay, if nothing is being supplied to any of these circuits then, check the wiring between the relay and the fuse board. If both relay circuits are getting voltage, push down the horn button and probe the circuit from the relay to the horn button for ohm readings to ground. If there is no continuity then go for an open circuit; if you do not get an open circuit then replace the horn button. If there is continuity through the horn button to ground, make test for open or short circuit from the relay to the horn. For replacement, note that there are two horns: on 2004 and earlier Highlander and 2003 and earlier Lexus models one is located in front of the condenser and the other below and in front of the engine compartment fuse and relay box while on 2005 and later Highlander and 2004 and later Lexus models both horns are located in front of the condenser. For the latter models, unbolt the radiator support trim panel and the panel and the grille from the radiator support. Remove the horns; on the cover beneath and forward of the fuse and relay box, you are required to unplug the electrical connector and then remove the mounting bracket bolt. To release the horn(s) situated in front of the condenser, the electrical connector should be disconnected the mounting bracket bolt, and also should be removed. Last of all, you need to unscrew the bracket bolt, and basically going about the process in reverse is installation.
