Hello. If you have an issue with one of the lights not working in the rear of your car under normal conditions, but yet it will work when you use the keyless entry then the issue is not in the light itself. Your car uses a smart junction block for the rear lights which is essentially a computer within the fuse panel. This computer is what usually fails. In some cases it is because the system recognizes a short an it can be reprogrammed, but in other cases it is because the computer is bad. I usually test the circuit electrically first to see if it is lacking voltage from this system. This would tell me where to start.
