you can make some assumptions and just run new wire. assumptions might be wrong.
there are ways to test. and that is how you are going to find what the problem is.
sometimes just by passing all of the old stuff is faster. I personally really despise doing it that way.

Test from the ground terminal (outer barrel if an incandescent type holder) in a rear turn signal to chassis ground - you should find continuity.
Test from the hot terminal (the center contact(s) of an incandescent type holder) in the same lamp fixture. - You should NOT find continuity. If you do, you have a direct short to ground and need to fix the situation.
One way to fix it is to find where the short is.
Another is to determine what area the short is in and isolate that area (cut the wire on both sides of the short) then install a new piece of wire, properly labeled for later trouble shooting if needed.
Either way you go, you need a good understanding of exactly what you're doing.
