* Ignition Switch: This is the most common cause. The switch itself might be worn out or failing internally. The contacts might not be fully disengaging, allowing current to flow even when the key is removed. This is exacerbated by age and wear.
* Ignition Switch Wiring: Worn, frayed, or shorted wiring connected to the ignition switch can cause a similar problem. A short circuit could be completing the circuit even without the key's engagement.
* Neutral Safety Switch (Automatic Transmission): If your Maverick has an automatic transmission, the neutral safety switch prevents the car from starting unless the transmission is in park or neutral. A faulty switch might be sending the wrong signal, allowing the starter to engage even when the key is out.
* Starter Solenoid: Though less likely to be the *sole* cause, a faulty starter solenoid could be sticking or not fully disengaging. This is more likely to manifest as a continuous cranking *while* the key is in the "start" position, but a sticking solenoid *could* contribute to the problem after key removal.
* Wiring Harness Issues: A problem somewhere in the main wiring harness, perhaps a damaged wire rubbing against a metal part, could be creating an unintended ground or short circuit.
* Steering Column Issues: Less common, but potential damage or wear within the steering column itself, impacting the ignition switch's mechanism.
Troubleshooting Steps:
1. Safety First: Disconnect the negative battery cable before attempting any serious troubleshooting.
2. Check the obvious: Inspect the ignition switch and its wiring for any visible damage, corrosion, or loose connections.
3. Neutral Safety Switch (if applicable): Check the operation of the neutral safety switch. Make sure it's properly connected and functioning correctly. Sometimes a little adjustment or cleaning can resolve this.
4. Tap the Starter Solenoid: (With the battery disconnected!) Gently tap the starter solenoid with a wrench or hammer. This might dislodge a stuck part, but it's not a long-term solution.
5. Professional Help: If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic. Improper electrical work can lead to further damage or even a fire. A mechanic has the tools and experience to properly diagnose and repair the issue.
Ignoring the problem is dangerous. Leaving the battery connected while the starter engages can drain the battery and potentially damage the starter motor itself. Get it checked out soon!
