turn signal not working

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Versa. From what you've described, the issue could be related to the body control module (BCM) if resetting it temporarily resolves the problem. The BCM controls various electrical functions in the vehicle, including the turn signals. If it's malfunctioning, it could be causing the left turn signal to behave erratically, even if the bulbs are fine. You might also want to check the wiring and connectors associated with the BCM for any signs of damage or corrosion, as these can cause intermittent issues. Even though the bulbs seem good, replacing them could be an inexpensive first step in this diagnosis. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
