* Battery: While the wipers work, the battery might still be weak. A low charge might be enough for low-draw accessories like wipers but insufficient for the high current draw required by the starter motor. Have the battery tested with a load tester, not just a voltage check.
* Starter Motor: This is a very likely culprit. The starter motor might be failing, seized, or have faulty wiring. A clicking sound when you turn the key is a classic sign of a bad starter. No sound at all suggests a problem with power getting *to* the starter.
* Starter Solenoid: This is a relay that controls the starter motor. A faulty solenoid will prevent the starter from engaging even if the motor itself is good. You might hear a clicking sound coming from the solenoid area (near the starter).
* Ignition Switch: This switch sends power to the starter. A faulty ignition switch can prevent power from reaching the starter, even if the battery and starter are fine.
* Neutral Safety Switch: This switch prevents the car from starting unless it's in Park or Neutral (automatic) or Neutral (manual). A faulty switch will prevent the car from starting regardless of the gear position. This is more likely on an automatic transmission.
* Wiring: A broken or corroded wire in the starting circuit can interrupt the flow of power to the starter motor or solenoid. This could be anywhere between the battery, ignition switch, starter, and solenoid. Look for signs of damage or corrosion in the wiring harness.
* Security System (if equipped): If your Contour has a factory or aftermarket alarm or immobilizer, a problem with the system could prevent the car from starting.
Troubleshooting Steps:
1. Battery Test: Get the battery load tested at an auto parts store. A voltage test alone isn't sufficient.
2. Listen Carefully: When you try to start the car, listen closely for any clicking sounds. The location of the clicking sound can help pinpoint the problem.
3. Check Connections: Inspect all battery cables and connections for corrosion or looseness. Clean them if necessary.
4. Check Fuses and Relays: Consult your owner's manual for the fuse and relay locations related to the starter. Check for blown fuses.
5. Neutral Safety Switch (Automatic Transmission): Ensure the car is in Park or Neutral. If you suspect the switch, it might need replacing.
6. Have it Checked Professionally: If you can't identify the problem yourself, taking it to a mechanic is the best option. They have the tools and experience to diagnose the issue quickly and efficiently.
Don't assume it's just the battery because the wipers work. While a weak battery is possible, several other components in the starting system could be at fault. The diagnostic steps above are a good starting point.
