Hello guys, did a quick search and found an old topic but the fix is related to an alarm system.
I Don't have an alarm and my 03 Taco is stock with no extra lights or anything, so far all the fuses are Ok, day or night the lights stay on, with headlights on/off, light switch on/off makes no difference.
Only way to turn them off is by removing the fuse for the tail lights or by disconnecting the battery.
Any ideas where do I need to start looking?
edit: runs very rough, almost to the point of shutting off, runs normal on the road
