My wifes 99 GC 3.8l has started spontaneously blinking on the turn signals. We hear the relay clicking and sure enough the lights outside will flash. Have there been any other issues with the switch,relay orBCM in this regard. It will go days without doing it and then do it for a few minutes at a rip. thanks for any input.

 

whats it do exactly.. blink fast? stay on? what do you mean by 'spontaneous'

 

just comes on by itself at normal speed. no pattern to when it does it. just starts blinking.

 

i am going to assume its the LEFT blinker? if so .. ya need to check the blinker switch out..

 

My windshield wipers dp the same thing. Annoying isn't it?
