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.

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.

Where is the location for the relay turn signal 2007 cobalt

You won't find it because........there isn't one. The BCM (body control module) controls the flash. If you have no sound it could be a defective speaker.

Asked this on 12/20 no response so asking again. 95 Hyundai elantra. Turn switch works part time. Put another used switch in but still same issue. When it's out nothing works, no turn, no hazard, no...

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.

Issues with turn signal in my 2001 Oldsmobile Alero. Hazard lights and right/left turn signal emit a very loud buzzing, then gets stuck. It does not work most of the time, or when it does, it buzzes...

Sounds like you have a bad multi-function switch or signal switch they are the same thing.This will fix the cruise control but,your other problem is your hazard warning switch replace it to.This will fix both of your problems.P.S you can get both of these from for less than $60.00.

Im trying to change my fuses for my hazrard lights. on a G6 2006 poniac. i cant find it in the manual. don't really know if thats what you do, cause when i push the hazrard button they don't work.

This is not fuse, is an flasher, and maybe is integrated with hazard & turn signal module.

Also need review this RECALL

Hope helped with this. Good luck.
