Bad rear running lights both sides

Hello,

It sounds like you have a lighting module located on the under side of the dash on the right side that is going out but to be sure lets remove the electrical connector and check it for corrosion. Here is the wiring diagrams for the lights so you can see how they work.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
