Pretty new here but need some help. My car came with aftermarket LED tail lights. My turn signals no longer work on the tail lights only. Front and side markers are fine. I had a Lois ground wire in the board and re soldered it and then the drivers turn signal also stopped working after that. Checked all the fuses, no codes, no fast blinkers in the front, solder points look good etc. I tried cleaning the pins on the connectors and the blinkers turned on once or twice after but immediately stopped. Any clues as to what is happening?
