Full disclosure up-front: I have aftermarket sequential turn signals, along with Diode Dynamics Elite Max headlights which use a pigtail for tapping into DRL and turn signal functionality, and lastly I have spliced into the turn signal lead (in said pigtail, post OEM harness) to feed a switchback module that I’m using for extra signals/fogs.
Okay, yes - that’s a lot of variables to introduce, and a lot of new points of failure. However, so far everything has worked perfect and reliably (for a few weeks now), and the failure seems to be unrelated to what I actually spliced into.
Here’s the issue: I recently drove through about 5 hours of nonstop downpours. Everything was still fine for a couple days. Today after about 3 hours of driving in dry weather, I flip on the left turn signal and it says the light is out. Couldn’t inspect it till I got home, but basically it stopped sending power to the turn signal lead itself as all my turn signals were out, not just the fender light which has the feedback loop for bulb-out error.
After getting home and turning it off, it was still malfunctioning (verified when trying to lock/unlock the doors). I turned the Jeep back on and…it fixed itself. No error, signals worked fine. They proceeded to work fine on a subsequent 4 hour drive.
So my question is…where do I start looking? I’m wondering if it possibly shorted because of the rain, but everything is heat shrunk and wrapped very well. Is it possible the switchbacks drew too much power and the 12v return for the bulb-out failed (is that even how it works)? Also…how could it self correct? Does the system hold transient memory of a single failure, and stops bothering to send the turn signal power until it resets?
