i have a 2003 tj and the flasher relay just buzzes away whe the blinker is not on, the blinkers/hazards work just fine. i replaced the light switch/blinker switch and the flasher with new just recently and it is still doing this. any ideas?
I have never heard of this before,not from the flasher anyway.Is it the same buzz as when you leave the lights on,door open,keys in the ignition???Any of those the same buzzing noise?If so I would say it is something else that is triggering it and a coincidence that it stops with the turn signals or flashers are on.I would start by pulling the door defeat fuse and see if it stops.Other than that I would say we are going to need a little more info.
Are you 100% sure it's coming from the flasher relay??? I mean you hear it and can pull the relay out and it stops buzzing right???If that is the case I see you replaced the switch and the flasher but have you tried to replace the relay also???I just have never seen a relay buzz and have to wonder if it isn't the door buzzer or something else but if certain it being the relay I would swap it out with another and see if that stops it.
