Guide to the 1987-1997 Chevrolet Impala & Caprice Turn Signal Switch
Having trouble with your turn signals, wipers, or high beams? Your multi-function switch is likely the culprit.
- This is a multi-function switch that controls turn signals, headlights, and wipers; a failure can affect any of these systems.
- A bad switch can cause your brake lights to fail. Verify their operation immediately if you suspect a problem.
- Replacement is moderately difficult and requires special tools like a steering wheel puller and lock plate compressor.
- Before replacing the switch, check for simpler issues like burned-out bulbs (for fast flashing) or a bad flasher relay.
Understanding the 1987-1997 Model Years
It's important to know that the "Impala" name was used for the high-performance Impala SS from 1994-1996 during this period. The part is also shared with the Chevrolet Caprice, which was produced from 1987-1996. Both cars are built on the same GM B-body platform, so this turn signal switch fits both models within these years. When searching for this part, looking for a 1991-1996 Caprice or a 1994-1996 Impala SS will yield the correct results.
Common Symptoms of a Failing Turn Signal Switch
When this switch starts to fail, it can cause confusing problems that don't always seem related to the turn signals. Here are the most common signs that your switch needs to be replaced:
- No Turn Signals: The most obvious symptom is when your turn signals don't work at all, either on one side or both.
- Brake Light Failure: A bad switch can sometimes interrupt the brake light circuit, which is a major safety hazard. One owner reported that their brake lights wouldn't work unless the lever was perfectly centered.
- Signals Don't Cancel: The switch may fail to "click off" after you complete a turn, leaving the blinker on.
- High Beams or Wipers Acting Up: Since this is a multi-function switch, you might find your high beams turn on by themselves or your wipers won't work correctly.
- Hazard Lights Don't Work: If your hazard lights aren't working but the turn signals are, the problem could still be in the switch assembly.
Before replacing the switch, it's a good idea to check the simple things first, like the turn signal fuse and the flasher relay, which is a small, inexpensive part located under the dashboard.

A faulty turn signal switch on these cars can prevent your brake lights from working. Have a friend stand behind the car while you press the brake pedal to confirm they are functioning correctly before you drive.
Choosing the Right Aftermarket Turn Signal Switch
For a vehicle of this age, aftermarket parts offer excellent value. The quality can be just as good as the original, especially with trusted brands. Here’s a look at the available options.
Brand Tiers
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP), often sold as Standard Ignition, is a highly respected brand known for making parts that meet or exceed original factory quality. Technicians and DIYers trust them for reliability and durability, making them a top choice if you want a fit-and-forget repair. They are known for rigorous testing and using high-quality materials like copper alloy conductors.
- Standard Aftermarket (Rostra Powertrain): Rostra is well-known for its electronic components, including cruise control systems and switches. They manufacture a variety of OE-style replacement switches and are a solid, reliable choice for a replacement part.
- Value/Economy (Replacement): "Replacement" branded parts are a budget-friendly option. They are designed to be a direct fit and will get the job done. However, the materials and internal components may not be as robust as premium brands, so long-term durability might be a concern for some owners.
OEM vs. Aftermarket Quality
For the 1987-1997 Impala and Caprice, a premium aftermarket switch from a brand like Standard Ignition is often the best balance of quality and cost. The original GM parts (AC Delco) are excellent but can be harder to find and more expensive. A good aftermarket part will restore original function without the high dealer price tag.
Cost of Replacing a Turn Signal Switch
| Part Type | Estimated Cost |
|---|---|

| Shop Labor | $150 - $250 |
| Total Estimated Cost | $188 - $324 |
Cost estimates are based on national averages and may vary by location and vehicle specifics.
Frequently Asked Questions (FAQ)
Can I replace the turn signal switch myself?
Yes, this is a DIY-feasible job, but it is moderately difficult. The process requires removing the steering wheel, which involves using special tools like a steering wheel puller and a lock plate compressor. If your car has an airbag, you must disconnect the battery and wait several minutes before starting work to avoid accidental deployment. If you are not comfortable with this, it's best to leave it to a professional mechanic.
🎬 See a step-by-step walkthrough of the Impala SS switch replacement.Why do my high beams or wipers turn on with the turn signal?
This happens because all of these functions are routed through the same multi-function switch. Over time, the internal contacts wear down and can cross-connect, sending power to the wrong component. This is a classic sign that the entire switch assembly needs to be replaced.
My turn signals blink really fast. Is the switch bad?
A fast-blinking turn signal, often called "hyper-flash," is almost always caused by a burned-out bulb on that side of the car. The system is designed to do this to alert you to a bad bulb. 🎬 Watch a quick troubleshooting guide for non-working Impala turn signals. Check and replace your front and rear turn signal bulbs before assuming the switch is the problem.
Do I need any special tools for this job?
Yes. To get the switch out, you will need to remove the steering wheel. This requires a steering wheel puller and a steering wheel lock plate compressor tool. These can often be rented from auto parts stores.
