1980 911SC, Where did my brake lights go?
Brake lights used to work now they don't?
Tail lights, running lights, blinkers, backup lights, emergency flashers all work. Just no bake lights. The fuse looks fine. What do I check. |

Pressure switches on the master cylinder, that is what makes the lights work.

Remove one of the plugs to either switch and jumper from terminal 81 to 82a of the connector. The brake lights should illuminate and the Brake Failure warning lamp should start flashing.

ok, brake lights work when plug is jumped. Now what? Do the pressure switches need cleaning or just replaced?
Is this a pressure switch that I can get at my local parts store or another porsche only part? thanks for the help |
