It sounds like something inside of the switch itself failed.

But there is hope, but it takes a bit of time, 4 rectifiers, some hookup wire and some electrical tape to make things look pretty- assuming the notion of a replacement unit is out of the question.

I am not sure if the normal GM color codes of todays vehicles for stop/ right turn/ left turn/ running apply to that one or not.

What it amounts to is wiring the front turn signals to their corresponding rear signals BUT with a rectifier to keep other lights from lighting(1N4001 should be adequate, or other 1N400# series- Radio Shack or other electronic supplier carries them), with the stripe on the rectifier being attached to the wire to the rear lights.

Find the wire from the brake switch that would energize the brake lights, this will have no voltage presentwhen brakes are not applied, and the other wire is always hot- if it is the design I think you are describing. From this wire, attach to two rectifiers- unstriped end- with the striped to attach to the striped end of the first rectifiers installed one for right, one for left.

As long as the turn switch remains functional for the front lights, the rear lights will function correctly, and the rectifiers are there to block current from going to the wrong lights. This also works if the brake light switch gets moved to the bolt that attaches the brake pushrod to the pedal itself.

This system does work as I have done it to two vehicles with no problems, and the repair lasts as long as the remaining portion of the old switch.
