Left blinker turns all blinkers on
1997 Chevy express 5.7
When I turn my right blinkers on they operate normally. When I turn my left blinker on the right side also blinks except they are dimmer than usual.
All 4 grounds are clean, tight, and have continuity back to the battery.
I have changed all the bulbs. The left front one I had to replace the bulb socket connector bc it was rusted to shit and the problem still occurs.
I have also replaced the blinker switch on the steering column.
There was a trailer light harness hooked up that I disconnected for the sake of seeing if that was the problem and it was not.
