Symptom - No rear brake lights. Left turn signals not working but blinker relay "Sounds" like only one way contact movement. However - Right turn signal lights work fine and blinker relay "sounds" normal.
Diagnosis so far: Purchased new turn signal relay and fuses.
I pulled the left rear running Lt/Turn indicator apart and tested the harness and the bulbs on an independent 12 volt source. All tested fine.
With new equipment installed and through repeated testing...
There are two different fuse locations. Turn indicator and Brake/Hazards
Pushing on brake pedal causes instant blowing of Brake/Hazards fuse
Key on, tuning on left turn signal blows turn signal fuse instantly
Turning on emergency flashers causes instant blowing of Brake/Hazard fuse
I noticed a transistor (3 Prong clip) in same harness and on same mount block as the signal relay so thinking this might be causing a direct short I disconnect the clip and run all the same tests with the same outcomes. (No solution or benefit)
I don't know if this transistor is part of the lighting circuit or not but disconnecting it did not cause any solution to the problem.
So now I still have the right blinker but no left blinker, no emergency flashers and no brake lights. If I put in fuses and press the left turn signal before I press the brake pedal, then not even the right turn signals work because the turn indicator fuse blows before the brake fuse blows and so there are no lights at all ( brake or turn indicator)
All other lights in the vehicle seem to be working fine.
All other electrical circuits in the vehicle seem to be working fine.
Do you have any ideas or knowledge about my dilemma?
