My 98 has a nearly constant buzzing while driving under the dash. It would stop buzzing whenever a turn signal was used. Tracked the buzzing and its the turn signal flasher buzzing.

Searching, most people report buzzing when the turn signal switch is bad but they also reported one side wasnt flashing when used. My turns and hazards work just fine. Should i replace the turn switch? Not sure what else would cause it.

 

Well i ordered an ebay switch. Ill update this for future searches if it fixes the issue.

 

any update on this?

did the switch fix the problem?

 

Buzzing electronics makes me think there is an arc of electricity between two points, which can easily cause an electrical fire. If it were me I would definitely replace it.
