Expert Reply:

That means that you have a short between the left and right turn signal circuits. Most likely this is on the vehicle side of the wiring. Try using a circuit tester like part # PTW2993 to test for voltage on the pins with the green and yellow wires to see if they both flash with either blinker. If so, trace the wiring up and look for any cut or exposed wiring between the two circuits and fix as needed.
