1989-1993 Buick Regal Ignition Switch: A Guide to Replacement
Is your Regal having trouble starting or stalling unexpectedly? Your ignition switch might be the problem.
- A bad ignition switch can cause a no-start condition or dangerous stalling while driving.
- The major GM ignition switch recalls of the 2010s do NOT apply to the 1989-1993 Buick Regal.
- Standard Ignition is a premium aftermarket option, while Rostra offers a solid, standard replacement.
- Replacement is a moderately difficult DIY job that may require accessing the steering column.
Is Your 1989-1993 Buick Regal Ignition Switch Failing?
If your Regal won't start, stalls while driving, or has flickering dash lights, a bad ignition switch is a likely suspect. Over time, the electrical contacts inside the switch wear out, leading to a poor connection. This can leave you stranded or, worse, cause the engine to shut off while you're on the road. This guide will help you understand the symptoms and choose the right aftermarket replacement part.
Common Symptoms of a Bad Ignition Switch
- Car Won't Start or Crank: You turn the key and nothing happens. The battery is good, but the switch isn't sending the signal to the starter motor.
- Engine Starts, Then Immediately Stalls: The car may fire up for a second and then die. This can happen if the switch provides initial power but can't maintain the connection for the ignition and fuel systems to keep running.
- Electrical Accessories Fail Intermittently: Your radio, dashboard lights, or heater may cut out randomly. This often happens when going over bumps, which can jiggle the worn contacts inside the switch.
- Key Feels Fine, But Nothing Works: The key turns smoothly in the lock cylinder, but the car doesn't enter the 'accessory' or 'on' position correctly. This points to the electrical switch behind the mechanical lock.
Important Note on GM Recalls
You may have heard about major GM ignition switch recalls. Please be aware: those recalls from the 2010s affected much newer vehicles (like the 2004-2005 Regal and Chevy Cobalt) with a different design. Searches of the NHTSA database show no major recalls for the ignition switch specifically on the 1989-1993 Buick Regal models.
Choosing the Right Aftermarket Ignition Switch
For a vehicle like the 1989-1993 Regal, aftermarket parts are the most common and cost-effective solution. Original Equipment (OEM) parts may be discontinued or difficult to find. Here’s a look at the available aftermarket brands.
Brand Tiers: Standard vs. Premium Aftermarket
Standard Ignition (Premium Aftermarket): Standard Motor Products (SMP) is a well-regarded brand in the industry, often considered a top-tier aftermarket choice. Mechanics trust their parts for fit and durability, and they are sometimes an original equipment supplier to car manufacturers. Choosing a Standard Ignition switch is often seen as a safe bet for a long-lasting repair.
Rostra Powertrain (Standard Aftermarket): Rostra is a known manufacturer of automotive electronics, including switches and sensors. While perhaps more famous for other components like cruise control systems, their ignition switches offer a reliable and more budget-friendly alternative to premium brands. This is a solid choice for a dependable, standard replacement.

Frequently Asked Questions (FAQ)
Is it hard to replace the ignition switch on a 1989-1993 Regal?
It is a moderately difficult job. It requires removing the plastic covers on the steering column to access the switch. Depending on whether your car has a tilt steering wheel, you may need to remove the steering wheel itself, which requires a special tool called a steering wheel puller. For a beginner, this can be challenging. It's a feasible DIY for someone with mechanical experience, but many owners choose to have a professional handle it.
Is the ignition switch the same as the ignition lock cylinder?
No, they are two different parts that work together. The lock cylinder is the mechanical part you put your key into. The ignition switch is the electrical component that the lock cylinder turns. If your key is physically stuck or hard to turn, the lock cylinder is the likely problem. If the key turns fine but the car has electrical issues or won't start, the ignition switch is the more likely culprit.
Can I drive my Regal with a bad ignition switch?
It is not recommended. The biggest risk is that the switch could fail while you are driving, causing the engine to stall. This would result in a sudden loss of power steering and power brakes, creating a serious safety hazard. It's best to get the vehicle repaired as soon as possible.
Will a new ignition switch come with new keys?
No. The ignition switch is a purely electrical part and has nothing to do with your keys. The ignition lock cylinder is what matches your keys. You will continue to use your existing keys after replacing only the ignition switch.
