Recently my left side signal stopped blinking, but still illuminated. Then it stopped working entirely. Both rear signals were and front signals working fine. Then, both front signals also stopped completely, not illuminating or anything. All of the bulbs are fine. The turn signal fuse is fine. I saw that the housing around one of the front signals looked kind of dumpy, so took that apart and cleaned it. So now: both front signals work again. And now BOTH side signals illuminate but do not blink! There is only one flasher relay, so if that was bad none of them would be working right? Kind of stumped. The vehicle is a 1996 Nissan Hardbody 2WD
