1. Battery and Connections:
* Battery voltage: Use a voltmeter to check the battery voltage. It should read around 12.6 volts when not under load. Anything significantly lower indicates a weak or dead battery.
* Battery terminals: Inspect the battery terminals and cables for corrosion, looseness, or damage. Clean them thoroughly if necessary with a wire brush and baking soda solution. Tighten any loose connections. Corrosion can significantly impede current flow.
* Cables: Check the cables themselves for any breaks or damage. A bad ground cable is a common culprit.
2. Ignition System:
* Key: Try a spare key if you have one. A faulty key transponder can prevent the car from starting.
* Ignition switch: A failing ignition switch can prevent power from reaching the starter. This is less common but possible.
* Neutral Safety Switch (Automatic Transmission): Make absolutely sure the car is in Park (or Neutral if it's a manual). A faulty neutral safety switch will prevent the starter from engaging.
3. Starter Motor:
* Starter Relay/Solenoid: This is a component that often fails before the starter itself. It's a smaller, cheaper part to replace. You may hear a clicking sound from the relay when you turn the key, indicating a problem here. Often located near the battery or under the hood.
* Starter Motor: If all else fails, it could be the starter motor itself. However, directly testing this usually requires some expertise and specific tools.
4. Other Possibilities:
* Fuses and Relays: Check the fuses and relays related to the starting system in the fuse box. A blown fuse is a quick and easy fix.
* Security System: If your car has an aftermarket or factory security system, it might be preventing the car from starting. Check the system's status lights or consult your owner's manual.
* Alternator (less likely): While less likely to directly prevent starting, a completely failed alternator could mean your battery is too depleted to turn the engine.
Troubleshooting Steps:
1. Start with the simplest: Check the battery voltage and terminals first. This is the easiest and most common cause.
2. Listen carefully: When you turn the key, do you hear any clicking sounds? This can help pinpoint the problem area (relay, starter solenoid).
3. Visual inspection: Look for any obvious signs of damage to wires, connections, or components.
4. Consult a manual: A repair manual specific to your 1997 Chrysler Sebring JXI Convertible will be invaluable for identifying components and troubleshooting steps.
If you're not comfortable working on your car yourself, it's best to take it to a qualified mechanic. They have the tools and expertise to diagnose the problem accurately and efficiently. Attempting to fix the starter without proper knowledge can be dangerous.
