Yeah my brake light and turn signal stopped working on the driver side .

Your problem is most likely to be the TURN SIGNAL AND HAZARD FLASHER UNIT

For test purposes you can swap sides with the taillight assemblies to see if problem follows light. You will likely find that to be the case - you can actually purchase the light assembly cheaper than the necessary replacement components - - $21.00 on eBay with FREE shipping ... . Problem is GROUND CIRCUIT inside the circuit board on light assembly.. Good luck!
