My turn signals are working strangely. All bulbs are good. When the lights are off the turn signals work normally. 86 Firebird.btw. The front side markers blink in time with the front turn signals but the rears do not. With the lights on it gets weird. With just the parking lighs on, the passenger side turn signal blinks slowly and the passenger front side marker light blinks out of phase with the turn signal. The driver side turn signal comes on and freezez while driver side marker light dims. With the heads on the driver side does the same thing as when the parking lights were on. The passenger side blinks very very slowly like two or three times a minute. Obviously something is wired wrong somewher. Anyone got any idea on what it is or how to diagnose it?

 

Yeah me too. I guess I'll start by yanking the side maker bulbs and see what happens.
