When I turn on a turnsignal, I hear this buzzing sound and the lights don't blink. But when I turn the emergency blinking lights (all 4 turnsignals blinking at the same time) they work. How come? This used to happen before in a more inconsistent manner (sometimes the turnsignals would work, but sometimes I'd hear the BUZZing sound). Now it's more consistent and the turnsigals aren't working.
Thanks.
Howdy Joe, folks
Since the emergency lights are OK, I'ld suspect the "turning signal switch" . What I mean by that is the electic stuff connected to the turning signal lever. It probably isn't making contact somehow when you want to do so. You'll probably get the same sound if your switch does work, but you don't push the lever up or down far enough.

Does the car has a seat belt reminder light, and is it blinking at the normal rate? The reminder light uses the same blink relay as the turnsignals. The relay is an old fashioned electromechanical device (at least in my -85 245) and, since it's function is load current dependent, it can be worn out in such a way that it functions normally for the load of all six lamps, but not for only three. Maybe you should try with another relay?
