Turn signal buzzing in off position but not on/hazards work with buzzing all the time
I saw your response to a similar problem asking if it's only when you turn left or right. My problem is that the flasher buzzes when the signal is off, but the buzzing stops when i turn the left or right switch on. Hazards do work but doesn't effect the buzzing at all it still stays on. I jumpered the ground from the flasher, and the buzzing still was there. I found out the the cause of buzzing was the wire that goes to the turn switch and a white box, I have the service manual for this car from the dealer and all i can see is tha the white box is a "convenience center" it controls the alarms for the seatbelt/headlight/key in ign/and interior lights. I unplugged the switch wire and it stil buzzed, i connected it back and unplugged the white box and the buzzing stopped and the turn signal/hazards worked fine. but now all alarms and interior lights don't work. going to the junkyard today to try to find the part since no autopart store carries it, ACDELCO site doesn't recognize the PN number and i won't even think of asking the dealer how much. the PN number on the white box is 16231519, not sure if that's for the entire part (including circuitboard) or just the box. I don't see any physcial damages to the circuit board. could you please let me know if you have any information in regards to this? thank you.

Re: turn signal buzzing in off position but not...
I sounds like you did a good job of isolating the source of the buzzing. I, too, was unable to locate that part number on the web. Changing the "convenience center" of course would be your best bet, but if you are unable to locate a replacement, you might want to try cleaning the plug that connects to the convenience center. It could be that it has oxidized pins that are creating an incomplete connection causing the flasher to buzz.
Best of luck to you.

The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.
Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.
Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.
Hi, My 1999 Elantra has a similar problem with the turn signal, I checked the switch itself and it worked fine, eventually I found out that it was the hazard switch that is faulty, to test it try and turn your car on, activate turn signal and press down on the top of the hazard switch or just fiddle with it. Just a thought, worked with mine. Good luck.
i have a similar problem but my left signal works, when i turn the right on it just does an annoying buzz sound. if you can think of any explination for such shinanogins help would be greatly appreciated
