View Full Version : Stumped on brake lights

My brake lights don't work.


The running (night) lights work. Turn signals work. So the bulbs and wiring are good (right?)


Because of this I replaced the brake light switch. Still don't work no matter how much pressure applied.


Any thoughts?


Btw, this is a 73 S3


Thanks,

I had the same thing...read about a batch of bad brake light switches, so I got another one. Problem solved.

try connecting the 2 wires that go to the brake light switch together. If the lights come on, it is the switch.

what bulb is the correct bulb for the tail/brakes?

So, the new switch I bought was bad.

The old switch I had was good.

The issue was actually a fuse that was blown that didn't look like it was blown. I found this out by replacing all the fuses just in case.

Lesson learned: A continuity tester/ohm meter is the only truly reliable way to assess the condition of a fuse (well, unless it's obviously blown, that is).

Indeed.

I can add it to the growing list of learned lessons from this ownership experience.

Don't worry, there'll be plenty more lessons where that one came from! Just wait till you get to the "I've got TONS of electricity everywhere, but my starter solenoid STILL acts like I have a dead battery" lesson. You'll really love that one. :)

I currently have same issue. Where is that fuse. Would be in the same place a 1967 station wagon.?

Thanks

No. The 2 fuses for the SIIA are inside the engine bay, on the bulkhead. And, the brake light switch is likely a hydraulic pressure switch located on the brake lines abeam the right-hand footwell (but on the inboard side of the chassis), and not a mechanical switch on the brake pedal tower like on the SIII.
