Electrical Issue

My 2015 chevy Colorado has a left rear turn signal fault. I replaced halogen for LED about a year ago with no issues. I am now getting a dash message that states there is a left rear turn signal fault. Indicator is blinking fast, rear LED light is completely off, turn signal and brake light are inop. The faulty light does light up when I unlock the truck with the fab but when the key is turned over the light goes off. When I unlock the truck with the fab, the right side light (working turn signal and brake light) does not light up. I tested fuses and relays, all seemed fine. LED lights came with a resistors, no issues there. I swapped the left side with the right side to see if the light assembly was faulty. The right side worked, the left side still inop. The LED light seems to be fine. Fuses checked, relays checked, light checked still not working. I bought the same LED lights again, still not working. Does anyone have any suggestions or ideas to solve this issue?
