Reverse lights on a 2013 ram 2500 not working. B1707 is the code on the left side code. Similar code for the right side (don't remember it off the top of my head). Bulbs are good and do not see a fuse on that circuit. Anybody know how to fix this?

Check the connections for corrosion

Both sides should not go out at same time if corrosion on bulbs

Removed left side housing , connector, bulb and reseated. Did not make a difference.

How about where the taillight harness meets the main harness.

How about where the taillight harness meets the main harness.

I don't see in any parts catalog a taillight harness.Do you have a part number?

I do not have a wiring diagram to know where all the connections are located. With both sides being out makes me think it is up stream somewhere.

I have not been up under the truck yet.
