- This is a very DIY-friendly repair that can be done with basic hand tools in about an hour or two.
Is Your Ignition Switch Failing?
A faulty ignition switch in a 1986-2007 Ford Taurus can cause problems that seem random and confusing. These issues often happen because the electrical contacts inside the switch wear out over time. This can cut power to the engine or other systems, sometimes without warning.
Common Symptoms for Ford Taurus:
🎬 Watch: 8 common symptoms of a failing ignition switch.- Car Won't Start or Crank: You turn the key, the dash lights may come on, but nothing happens. The starter motor is silent because the switch isn't sending it power.
- Engine Stalls While Driving: This is a serious symptom. The switch can lose connection from vibration or bumps in the road, cutting power to the engine and causing it to shut off unexpectedly.
- Starts and Dies Immediately: The engine might fire up for a second while the key is in the 'START' position but die as soon as you let it go to the 'ON' position. This means the switch isn't maintaining power to the ignition system.
- Flickering Dash Lights & Accessories: You might notice the radio, heater, or dashboard lights cutting in and out. This can happen if you jiggle the key or hit a bump.
Pro Tip: Try gently wiggling the key while the car is running (in Park). If the engine sputters, stalls, or the dashboard lights flicker, it's a strong sign the ignition switch is worn out.
Choosing the Right Aftermarket Ignition Switch
For a vehicle like the 1986-2007 Taurus, you don't need to pay dealership prices for an ignition switch. Quality aftermarket brands offer a reliable and affordable solution. The key is choosing a reputable brand.
- Standard Ignition (SMP): A well-respected name in the aftermarket, Standard often produces parts that meet or exceed original specifications. They are a solid choice for reliability.
- Dorman: Dorman is known for making a huge variety of aftermarket parts. They sometimes re-engineer parts to fix common factory flaws. While quality can sometimes be inconsistent depending on the part, for a common component like this, they provide a good value.
For this part, both Standard Ignition and Dorman are dependable choices that will restore proper function without the high cost of an OEM part.

Replacing the ignition switch is a relatively inexpensive repair. The main cost is labor if you have a shop do the work.

Important: There have been no major recalls for the ignition switch on the 1986-2007 Ford Taurus. A large Ford recall in the 1990s for ignition switch fires specifically excluded the Taurus.
Frequently Asked Questions
Is the ignition switch the same as the lock cylinder?
No. The lock cylinder is the mechanical part your key slides into. The ignition switch is the electrical component located behind or near it. If your key is hard to turn or gets stuck, the problem is likely the lock cylinder. If you have electrical issues like stalling or a no-start, the ignition switch is the more likely culprit.
How do I know it's the ignition switch and not the battery or starter? 🎬 See how to troubleshoot a no-start when your battery is good.
A bad battery usually results in a slow crank or a clicking sound. A bad starter might also click or make no sound. A bad ignition switch is unique because all the lights and accessories might work perfectly, but the car won't crank, or it will stall intermittently while driving.
Can I replace the ignition switch myself?
Yes, this is a common DIY repair for those with basic tools. It involves removing the plastic covers around the steering column to access the switch. You will need to disconnect the battery first. 🎬 Follow this step-by-step guide to replace the switch yourself. The switch is typically held on with a couple of small bolts and has a single electrical connector.
Will a bad ignition switch drain my battery?
Yes, it can. If the switch fails in a way that it doesn't fully turn off power to certain accessories or systems when the car is off, it can create a slow electrical drain that kills your battery overnight.
