1994 GMC Sonoma 4.3L V6 5 speed
Got a weird problem with my 94 Sonoma’s turn signals. My passenger side turn signal will illuminate, but will not flash, no matter if the headlights are on or off. When I turn on the flashers, my passenger side front side marker light & tail light will flash, but my passenger side right bumper light will only illuminate, not flash. The driver side is completely fine. What could be causing this?
