Ford Police Interceptor Utility Ignition Switch Guide (2013-2021)
Is your Police Interceptor Utility having trouble starting or stalling? Your ignition switch might be the culprit.
- A failing ignition switch can cause a no-start, stalling, or intermittent electrical issues; use the 'key wiggle test' to help confirm the diagnosis.
- This is a DIY-friendly repair that does not require reprogramming the keys.
- Be aware of a 2020 TSB for a no-crank condition that requires a software update, not a new switch.
- Due to the risk of the engine stalling while driving, a faulty ignition switch should be replaced immediately.
Is Your Ignition Switch Failing? Common Symptoms
A bad ignition switch in the Ford Police Interceptor Utility can cause confusing electrical problems that might seem like a dead battery or a bad starter. Because these vehicles often see heavy use, this switch can wear out over time. Look for these common warning signs:
- No Crank, No Start: You turn the key and get nothing but silence, or maybe a single click. This is the most frequent symptom. 🎬 See why your Explorer might not crank or start.
- Engine Stalls After Starting: The engine fires up but dies as soon as you let go of the key. This happens because the switch isn't keeping power flowing to the ignition system in the 'ON' position.
- Stalling While Driving: This is a serious safety issue. The switch can lose connection internally, cutting power to the engine and causing it to shut off unexpectedly.
- Flickering Lights & Accessory Problems: The dashboard lights may flicker, or accessories like the radio, power windows, and climate control might work intermittently or not at all.
- Key Feels Hard to Turn: While often a problem with the lock cylinder, a binding or worn internal mechanism in the switch can also make the key difficult to turn.
The Ignition Switch Wiggle Test
If you suspect the switch is bad, try this simple test with the vehicle in PARK and the engine running. Gently wiggle the key in the ignition without turning it. If the engine sputters, the dashboard lights flicker, or the engine stalls, you've likely found your problem: a worn-out ignition switch.
Vehicle-Specific Known Issues
2020 Models - No-Crank TSB: Some 2020 Police Interceptor Utility vehicles may have a no-start or dead battery condition that mimics a bad ignition switch. Ford issued Technical Service Bulletin (TSB) SSM 49128, which states the problem can be caused by software in the body control module (BCM) or other computers. A dealer may need to reprogram the modules before you replace any parts.
2020-2022 Models - Engine Fire Recall: Ford issued a major safety recall (NHTSA 24V598) for 2020-2022 models due to a risk of engine failure that could lead to an under-hood fire. While this is not caused by the ignition switch, it is a critical safety warning for owners of these model years.
Choosing the Right Aftermarket Ignition Switch
You don't have to go back to the dealer for this part. Aftermarket options offer a good balance of price and quality. Here’s a breakdown of the available brands:
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP) is a well-respected brand in the industry. Mechanics often trust them for electrical parts because their quality is very close to, and sometimes better than, the original factory part. For a critical component like an ignition switch, this is a reliable choice for long-term peace of mind.
- Mid-Grade Aftermarket (Dorman): Dorman is known for making a wide variety of replacement parts. Their quality can be inconsistent, with some parts lasting the life of the vehicle and others failing early. It's a popular choice that often gets the job done at a lower price, but it carries more risk than a premium brand.
- Economy Brands (Replacement, True Tech, VNE): These are typically budget-friendly, private-label brands. They are basic replacements that meet minimum specifications but may not have the same durability or precise feel as higher-end options. They can be a good choice if the budget is the primary concern.
Replacement Cost
| Part Source | Estimated Price Range |
|---|---|
| New OEM (Ford/Motorcraft) | $65 - $110 |
| New Aftermarket | $37 - $87 |
| Shop Labor Cost | $80 - $150 |
Frequently Asked Questions (FAQ)
Do I need to reprogram my keys after replacing the ignition switch?
No. The ignition switch is a separate electrical part. Your keys are coded to the ignition lock cylinder and the vehicle's anti-theft system, not the switch itself. You can replace the switch without any need for key reprogramming.
How do I know it's the ignition switch and not the battery or starter?
A bad battery usually causes a slow crank or rapid clicking noise. A bad starter often results in a single, loud click when you turn the key. A bad ignition switch, however, frequently causes complete silence, intermittent stalling while driving, or flickering accessory lights—symptoms the battery and starter don't typically cause. 🎬 Check this video to locate the ignition switch fuse and relay. The 'wiggle test' is also a strong indicator of a faulty switch.
Can I replace the ignition switch myself?
Yes, this is a DIY-feasible job for someone with basic tools. It involves removing the plastic trim panel under the steering column and a metal shield to get access. The switch is located on the back of the ignition lock housing. The main challenge is working in a tight space. 🎬 Watch this step-by-step guide to replacing the ignition switch yourself. The job typically takes about an hour.
What if I replace the switch and the problem continues?
In some cases, the problem may not be the switch alone. One owner reported that the wiring and the entire ignition lock housing also had to be replaced to fix their starting issue. If a new switch doesn't solve it, inspect the connector and wiring for damage, or consider the possibility of a software issue as noted in TSB SSM 49128 for 2020 models.
