Suggestion

Whether you replace this yourself, or have it done -- my local dealer service department replaces the switch for free as long as I buy the switch at the dealer's parts department (the service department also offers this free installation for light bulbs and fuses/relays and wipers) -- my advice would be to replace not only the brake light switch, but the clutch interlock switch (the switch that prevents the engine from cranking if the clutch pedal is not depressed) at least.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I assume the switch is failing. When I initially depress the brake pedal or press lightly my brake lights work. As soon as I press harder the go out. On immediate firm braking I get an initial flash of brake lights the nothing. No abs light on dash. Anything else to look for?

POST 2Original post

My Boxster exhibited the same behavior. Proved to be a brake light switch. If you can stand to contort yourself you can remove the old switch and install a new switch. The switch is not expensive. Whether you replace this yourself, or have it done -- my local dealer service department replaces the switch for free as long as I buy the switch at the dealer's parts department (the service department also offers this free installation for light bulbs and fuses/relays and wipers) -- my advice would be to replace not only the brake light switch, but the clutch interlock switch (the switch that prevents the engine from cranking if the clutch pedal is not depressed) at least. I would advise you to also consider replacing the switches above the clutch pedal lever and the brake pedal lever that switch off the cruise control when the clutch pedal or brake pedal is depressed.
