* On the transmission itself: This is the most common location. It's a small switch mounted directly on the transmission case, usually near the linkage that connects the shifter to the transmission. You'll likely see wiring connected to it.
* On the steering column: Less common on this model year, but possible. In this case, it would be integrated into the steering column's shift linkage mechanism.
Troubleshooting a faulty NSS:
Symptoms of a bad neutral safety switch include:
* Inability to start the truck: This is the most obvious symptom. The starter motor won't crank, even with the key in the "start" position.
* Intermittent starting problems: The truck might start sometimes but not others.
* Truck starting in gear: This is a safety hazard and indicates a serious problem with the NSS.
If you suspect a faulty NSS:
1. Visual Inspection: First, carefully inspect the switch for any obvious damage, loose wires, or corrosion.
2. Test the Switch (Advanced): You'll need a multimeter to test the switch's continuity. This requires understanding basic electrical testing and the specific wiring diagram for your truck's transmission. A wiring diagram specific to your year, make, model, and transmission type is crucial for accurate testing. These are often available online through repair manuals or Ford-specific forums.
3. Replacement: If the switch is faulty, you'll need to replace it. This usually involves disconnecting the wiring harness, removing the old switch, and installing the new one. Be sure to follow the instructions carefully and use the correct torque specifications for the mounting bolts (if any) to avoid damaging the transmission.
Finding a Replacement:
You can find replacement neutral safety switches at most auto parts stores. Be sure to provide them with the year, make, model, and engine/transmission information for your truck to ensure you get the correct part. Online retailers also offer a wide selection.
Important Safety Note: Always disconnect the negative battery cable before working on any electrical components in your vehicle. This will prevent accidental shorts and potential injury. If you're uncomfortable working on the electrical system yourself, it's best to take your truck to a qualified mechanic.
