Brake pedal switch replacement

[royp4]

I am posting this hoping it will benefit someone. I have a 2003 996 c2 cab. Recently the brake lights went out. After screwing with the brake pedal switch, I discovered that it needed to be replaced. Manually depressing switch with my finger showed that this was an intermittent problem. The interesting part of this is that I found that when the switch went out, neither the hazard flashers nor the cruise control would work. After replacing the switch, all these problems resolved. The switch is in a hard to reach location {of course}. While I could visualize the switch by lying on my back in the driver's side footwell, I had no room to manipulate. After a couple of hours of frustration and cursing, I found that I could manipulate and change the switch by sitting in the driver's seat and blindly removing and replacing the switch.

That's great advice - I have tried 3 times now to lie upside down in the footwell and try and 'see' the **** switch and it's honestly impossible with the air vent there and the knee stop trim for the dash. The Pelican article says you can see it if you lie in the passenger side and slide across but no amount of trying for me could do that either.

Is the switch mounted vertically above the pedal and do you have to twist it to unlock it from its mount?

The switch is mounted horizontally, and yes, you must twist it to unlock it from the mount. It's a tricky job but it can be done (since I have done it). Make sure you buy a OE Porsche replacement switch correct for your VIN, and also, there are two switches on the brake pedal, one for the brake lights and one for the cruise control. I believe the black switch is for the brake lights and the reddish one is for the cruise control. If you can't picture it in your mind, stick your cell phone under the dash and take a few pictures. Helps with orientation.

Thanks for the reply and much appreciated. Luckily I managed to find a video of the switch location which helps me visualise it much better - for reference for others in the future it is below

For the two switches, do you know which one triggers the gear stick unlock on the tiptronic gearbox as that's the one I'm trying to replace?

Basically I have to step on and off the brake pedal a few times (random amount) until it unlocks so I think it is the switch not triggering it consistently
