My turn signals don’t work either, since my steering wheel upgrade. After blowing 3 fuses I invested in a $3 15A circuit breaker, which will remain until I figure out the problem ;D
The issue is that they do work, only under certain conditions.
I’ve removed two towing harnesses so far and tried to get everything back to stock, but problems persist.
The front work as intended, both independent direction (left/right alone) and flasher.
The rears though, have problems.
I have no reverse lights (which I need to check the column pin), but my rear brake lights and the flashers work. So the bulbs are fine.
The issue is that I have no left turn signal and the right signal causes both to flash (like the hazard).
So the electrical connections are there. The bulbs work. There’s just something in the turn signals that’s messed up.
I’d like to replace the back half with a stock harness or the aftermarket one, but it’s not worth $125 to me if I’m going to rip it out when I do a full rewrite.
