Car Forum / Volvo Cars / June 2005'89 240DL: buzzing sound when turning on turnsignals?
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 > When I turn on a turnsignal, I hear this buzzing sound and the lights don't > blink.

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. CU Mathy Does the car has a seat belt reminder light, and is it blinking at th normal rate? The reminder light uses the same blink relay as th turnsignals. The relay is an old fashioned electromechanical device (a 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 loa of all six lamps, but not for only three. Maybe you should try wit another relay -- Lars Hoverfal Does the car has a seat belt reminder light, and is it blinking at th normal rate?
