For 1990-2009 cars only
Troubleshooting hints:
- Check condition of the Horn Circuit Breaker. If the circuit breaker is open, locate and repair the cause of the overload and replace the circuit breaker.
- Inspect the ground connection to make certain that it is clean and tight.
- Inspect the horn relay and make certain that it is securely fastened in the MaxiFuse® Block/Mini-Relay Center.
- Inspect for broken (or partially broken) wire inside the insulation. This condition could cause system malfunction but prove to test good in a continuity or voltage test with the system disconnected. These circuits may be intermittent or resistive when in operation. If possible test for a voltage drop when the system is operational.
- Inspect for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
