When I do left or right signal, I hear a quick static electrical buzz whenever the arrow lights up on the dash. It's not all the time, I'd say 50% of the time. Anyone know what it could be? Thanks.

 

Does your mdx make noise when signalling? Like the standard ticking turn signal sound? If it does, does it do it when making static or not? My guess is that the little speaker meant to make the ticking sound is blown and making a static sound.

 

Sorry for the late reply. I don't get notifications about replies. Anyways, yes, when I signal, the standard ticking sound is there 100 % of the time. When it does the buzz, it'll tick/buzz tick/buzz and the actual signal arrow on the dash will turn on/off as usual except it'll have a flicker to it.

 

That is the one thing I hate about this forum. Then it sounds 100% like something wrong with the wiring for the signals.

 

UPDATE: It was the Turn Signal/Hazard relay.

 

Thank for coming back and updating us!
