Subaru Impreza 1993-1998 Brake Light Switch: A Complete Guide
Fixing common brake light, cruise control, and shifting problems starts with this small but critical part.
- A bad brake light switch is a critical safety issue and should be replaced immediately.
- Symptoms include non-working brake lights, inability to shift from Park, and cruise control failure.
- This is a very easy and inexpensive DIY repair that takes less than 30 minutes.
- The major Subaru brake light switch recall does NOT apply to 1993-1998 models.
Is Your Brake Light Switch Failing?
A faulty brake light switch on a 1993-1998 Impreza can cause confusing problems. Because it's a simple part, the symptoms are usually straightforward. If you notice any of these signs, your switch is the most likely culprit.
- Brake Lights Don't Work: The most obvious and dangerous symptom. Someone needs to stand behind the car while you press the brake pedal to confirm this.
- Brake Lights Stay On: The switch can also fail in the 'on' position, leaving your brake lights permanently lit. This can drain your battery and confuse other drivers.
- Cruise Control Won't Turn On or Shuts Off: If the switch is faulty, the cruise control system may not engage, or it might shut off without you touching the brakes.
- Can't Shift Out of Park (Automatic Transmission): A safety feature called the shift interlock prevents you from shifting out of Park unless the brake is pressed. A bad switch means the car doesn't know you're braking, so the shifter remains locked.
Important Note on Subaru Recalls
You may have heard about a massive recall for Subaru brake light switches. It is critical to know that this recall does not apply to the 1993-1998 Impreza. The recall covered later models from 2008-2016 due to an issue with silicone contamination. Your first-generation Impreza uses a different, simpler switch design not affected by that specific recall. No recalls or Technical Service Bulletins (TSBs) are on record for the brake light switch on 1993-1998 models.
Choosing the Right Aftermarket Switch
For a simple part like this, the difference between OEM and a quality aftermarket part is minimal. The key is to buy from a reputable brand. Given the low cost, it's wise to avoid the absolute cheapest no-name options to ensure reliability.
- Premium Aftermarket (e.g., Beck Arnley): Brands like Beck Arnley focus on meeting or exceeding original equipment (OE) specifications for foreign vehicles. They are often considered a top-tier aftermarket choice, providing confidence in fit and function.
- Standard/Value Aftermarket (e.g., Dorman, Facet, Holstein): These brands offer a balance of quality and value. They are widely available and are a perfectly acceptable choice for this repair. Dorman is a common brand found in many auto parts stores, while Facet and Holstein are also established manufacturers.
Ultimately, any of the available brands will perform the job. The simple, 2-pin mechanical design of the switch for this generation Impreza is a proven and reliable technology.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Part | $6 - $17 |
| New OEM Part | $15 - $25 |
| Shop Labor | $50 - $100 |
| DIY vs. Shop Total | $10 vs. $70-$120 |
Common Ordering Mistake
Some parts listings mention a switch for vehicles "without cruise control". While most models use the same 2-pin switch, always double-check the fitment notes for your specific Impreza trim (L, LX, Outback Sport, etc.) to be certain you are ordering the correct part.
Can I Install It Myself? A Quick Guide
Yes, this is one of the easiest repairs you can do. It requires no special tools and takes less than 30 minutes.
- Locate the Switch: Look up under the dashboard, at the very top of the brake pedal arm. You will see the switch's plunger touching the pedal.
- Disconnect Wiring: Carefully unplug the two-wire electrical connector from the back of the switch.
- Remove the Old Switch: The switch is threaded into a bracket and held by a nut. Loosen the nut and unscrew the switch.
- Install the New Switch: Screw the new switch into the bracket until its plunger is fully depressed by the pedal arm when the brake is not being touched. Tighten the locking nut.
- Reconnect and Test: Plug the electrical connector back in. Have a helper confirm that your brake lights turn on when you press the pedal and, just as importantly, turn off when you release it. Test your cruise control function if equipped.
Frequently Asked Questions
Is it safe to drive with a bad brake light switch?
No. If your brake lights are not working, drivers behind you will not know you are stopping, which creates a high risk of a rear-end collision. This should be repaired immediately.
My brake lights work, but my cruise control doesn't. Could it still be the switch?
Yes. Some switches have multiple internal contacts. It's possible for the contact that controls the brake lights to work while the one for the cruise control system has failed. Given the low cost, replacing the switch is a good first diagnostic step.
Why can't I shift out of Park?
Your Impreza has a shift lock safety system. It requires a signal from the brake light switch to confirm your foot is on the brake before it will allow the shifter to move out of Park. If the switch is broken, the system never gets the signal.
Do I need to adjust the new switch?
Yes, proper adjustment is important. The goal is for the brake lights to come on with just a light touch of the pedal, without being so sensitive that they flicker on over bumps. After installing the new switch, check that there is minimal pedal travel before the lights activate.
