That only rules out the switch. I assume it is the ss relay behind the fuse box. in the smart junction box. The only way to see if the BCM is passing a signal on to the SJB is with the GDS software to look at the can bus.

would you recommend replacing the ss relay? or would there be any other circuit to test? id really like to diy this, with a bit of guidance :)

I would make sure there is no output to the fog lights on the SJB before I would rule it out. Other than that it is going to take a scanner to look at the digital signals.

The alternative is to wire them in to bypass the BCM.
You basically just need the harness, but this is all I can find with a quick search. You can maybe ask the seller if they can sell the harness separately for cheaper, but getting the whole thing, you can replace the turn signal switch and the lights just to narrow the problem.

Were the bulbs checked/replaced. Are these halogens or some weird aftermarket HIDs?
