1. The Obvious First Steps:
* Key Position: Ensure the key is fully inserted into the ignition. Sometimes a partially inserted key will trigger the buzzer. Try wiggling the key gently while it's in the ignition.
* Key Condition: Inspect the key for any bending, wear, or damage. A worn or damaged key might not make proper contact. Try a spare key if you have one.
* Steering Wheel Lock: Make sure the steering wheel isn't locked. If it is, gently jiggle the wheel while turning the key.
2. If the Above Doesn't Work:
The buzzer is likely triggered by a faulty ignition switch or a related electrical issue. This requires more involved troubleshooting:
* Ignition Switch Inspection: The ignition switch itself can fail. This is the most likely culprit if the problem persists after checking the key and steering wheel. Inspecting the switch directly is difficult and might require removing the steering column shroud (which can be complex depending on your mechanical skills). Look for any obvious signs of damage, corrosion, or loose wiring.
* Wiring Harness Check: Examine the wiring harness connected to the ignition switch for loose connections, broken wires, or corrosion. Pay close attention to the ground wires. A bad ground can cause all sorts of electrical gremlins.
* Neutral Safety Switch (if applicable): On some models, a malfunctioning neutral safety switch can prevent the car from starting and may trigger a warning buzzer. This switch ensures the car only starts in Park or Neutral. Check if your car has one and inspect its wiring and connection. It's often found near the transmission.
3. Solutions:
* Cleaning Contacts: If you find corrosion on the key, ignition switch, or wiring harness, try carefully cleaning them with a contact cleaner spray (electrical contact cleaner, not general-purpose cleaner).
* Replacing the Ignition Switch: This is often the ultimate solution. Replacing the ignition switch is a more involved repair and may require some mechanical skill and specialized tools. You'll likely need a replacement switch from a Mitsubishi parts supplier. There are repair manuals and videos online that can guide you through this process, but if you're uncomfortable working on car electrical systems, it's best to take it to a mechanic.
* Professional Help: If you're not comfortable diagnosing and repairing electrical issues, take your Mirage to a qualified mechanic. They have the tools and expertise to diagnose the problem accurately and perform the necessary repairs.
Important Safety Note: Working on the ignition system involves working with potentially live wires. Disconnect the negative battery terminal before attempting any repairs to minimize the risk of electrical shock.
Before undertaking any repairs, consult a repair manual specific to your 1995 Mitsubishi Mirage. This will provide detailed diagrams and instructions. Remember to always prioritize safety when working on your vehicle's electrical system.
