Wondering if anyone can help out have issues with turn signals on my 62 cadillac. All lights are working correctly, i only get the rear passengers blinker working and front passenger blinkers. Also, only my rear 'FIN' blinke is working, but not my rear tail light or front drivers blinkers or fog light they don't work. Wondering if it might just be my turn signal switch? should i remove steering wheel and clean up the turn signal switch? your input would be greatly appreciate it.
