I have an 87 Camaro sport coupe. with in the past week or so the right side turn signal will stop working then all of a sudden it will work again then the next day the left will stop working and then after a while start working. i have a 1987 Factory service manual, but couldn't figure out the wiring to save my life. Has anybody else experienced something like this? I have a feeling it might be the switch but not sure.
