2005 Honda Accord LX 4cyl

I am having an issue with the taillights on my car. The left brake light is out (running light works) and right running light is out (brake light works). I have tried changing the bulbs with no luck. Anyone have any ideas? Where would I find wiring diagrams for this? Is there an interior fuse box for this car? Thanks for your help

 

Since the right/pass side brake light is working - and I assume the third/high mount brake light - this sounds more like a wire issue than a fuse. One fuse for all of the brake lights.

Do you have a volt meter? On the left/drivers side, check to see if you are getting ~12v on the WHT/BLK wire when pressing the brake pedal.

Is this a 2 or 4 door car?
