The dreaded “brake light failure” warning on your Saab 93 dashboard can be a real head-scratcher. It signals a problem with your brake light system, a crucial safety feature that alerts other drivers when you’re slowing down or stopping. Ignoring this warning isn’t an option, as it could lead to dangerous situations on the road and even traffic violations.
This comprehensive guide dives deep into the common causes behind the Saab 93 brake light failure warning and provides practical solutions, whether you’re a DIY enthusiast or prefer professional help.
Understanding the Warning
The brake light failure warning usually appears as a message on your dashboard, accompanied by a lit-up warning symbol. This indicates a malfunction somewhere in the brake light circuit.
Common Causes and Troubleshooting Tips
Several factors can trigger the brake light failure warning in a Saab 93. Here are some of the most frequent culprits:
1. Blown Brake Light Bulbs
The most common and straightforward cause is a blown brake light bulb.
Solution: Inspect all your brake light bulbs, including the high-mounted stop lamp. If you find a blown bulb, replace it with a new one of the correct type.

2. Faulty Brake Light Switch
The brake light switch, located under the brake pedal, activates the brake lights when you press the pedal. A malfunctioning switch can prevent the lights from illuminating.
Solution: To test the switch, have someone observe the brake lights while you press and release the pedal. If the lights don’t illuminate, the switch likely needs replacement. This task often requires some mechanical aptitude, so consider consulting your owner’s manual or seeking professional assistance.

3. Wiring Issues
Worn-out, damaged, or corroded wiring in the brake light circuit can disrupt the flow of electricity, leading to a failure warning.
Solution: Carefully inspect the wiring harness connected to the brake light bulbs and the brake light switch. Look for any signs of damage, fraying, or corrosion. Repair or replace any faulty wiring as needed.

4. Blown Fuses
Fuses protect the electrical system from overloads. A blown fuse in the brake light circuit can disable the lights.
Solution: Consult your owner’s manual to locate the fuse box and identify the fuse responsible for the brake lights. Replace the blown fuse with a new one of the same amperage.
5. Faulty Body Control Module (BCM)
In some cases, a malfunctioning BCM, which controls various electrical functions in your Saab 93, could be the culprit behind the brake light failure warning.
Solution: Diagnosing and repairing a faulty BCM requires specialized equipment and expertise. It’s best to leave this to a qualified Saab technician.
When to Seek Professional Help
While some causes of a brake light failure warning are simple to fix, others require advanced knowledge and tools. If you’re unsure about any repair or can’t pinpoint the issue after basic troubleshooting, don’t hesitate to contact a trusted mechanic or your local Saab dealership.
Preventing Future Issues
Regular maintenance can help prevent brake light failures:
- Periodically inspect your brake lights: It’s a good practice to check your brake lights every time you fill up your gas tank.
- Replace aging bulbs proactively: Consider replacing your brake light bulbs every two years or so, even if they haven’t blown yet.
- Address minor electrical issues promptly: Don’t ignore flickering lights or other electrical gremlins. Addressing them early can prevent larger problems down the road.
By understanding the common causes of the Saab 93 brake light failure warning and following the troubleshooting tips outlined in this guide, you can ensure the safety of yourself and other drivers on the road.
