To add to the above did you replace the switch? It is known that some switches are improperly color coded. Regardless, this sounds like a TS switch or wiring connection problem.

Might be easier if you realize "what you have"

Here are the inputs and outputs of the TS switch

IN:
1.. full time hazard flasher power
2....full time switched brake lights
3....Power only in "run" position of key, is turn signal flasher power

OUT
1...left rear stop and turn
2...right rear stop and turn
3...left front turn and branch off to turn indicator lamp
4...right front turn and branch off to turn indicator lamp
