How to diagnose and replace a faulty horn on 2002 through 2008 Toyota Solara?

Before starting electrical diagnosis, check the fuses. To test the horn, disconnect the electrical connector and connect battery voltage to the horn terminal using a jumper wire. If the horn doesn't sound, replace it. If it does sound, check for voltage at the terminal when the horn button is pressed. If there's voltage, check for a bad ground. If no voltage, check the relay. If the relay is fine, check voltage in the power and control circuits. If no voltage, inspect wiring between the relay and fuse panel. If both circuits have voltage, check the circuit from the relay to the horn button for continuity to ground. If no continuity, check for an open circuit. If continuity, check for an open or short in the circuit from the relay to the horn. To replace the horns, locate them in front of the radiator, disconnect connectors, and remove bracket bolts. Installation is the reverse.

How do I perform horn diagnostics, troubleshoot issues, and remove the horn on 1997 through 2001 Toyota Solara?

Disconnect the electrical connector from the horn and test it with battery voltage. If it doesn't sound, replace it; if it does, check for voltage at the terminal when the horn button is pressed. If there's voltage, check the ground connection. If not, inspect the horn relay and its wiring. If both have voltage, test the circuit from the relay to the horn button. If absent, check for an open circuit or replace the horn button. If continuity exists, check for an open or short in the circuit from the relay to the horn. For removal, disconnect the connector and remove the bracket bolt. To reinstall, switch the removal steps going from the last step to the first step.
