It's built into the button you push in the dash to turn the hazard flashers on. GM has had a lot of trouble with those flashers and there was a recall on certain models. The part # is 10359580 and it lists for $24.15 plus tax.
the flasher relay is part of your 4way flasher button there should be a recall if its not working correctly
My flasher relay ( flasher if you will) is located in tne fuse panel on the front looking out at you. It is round.
I have a 1996 Sunfire and the 4way flasher is located on the top of the steering column.
I own an 89, so they should be set up the same. There are two separate flashers for the 4ways and turn signals. The 4way flasher shoud be clipped under the dash on the driver side and the turn signal flasher is plugged in under the dash on the firewall, also on the driver side.
In side the dash up under the steering wheel.
There is no flasher unit. Spray WD40 around 4way flasher switch on top of thesteering column. Operate switch a few times. Worked for me on my 94 T-Bird.
They are two separate circuits. Check the 4 way fuse then check the 4 way flasher relay.
YOU NEED TO REPLACE THE TURN SIGNAL FLASHER. IT WILL BE LOCATED ON OR VERY NEAR THE STEERING COLUMN UNDER THE DASH.
Check all of your fuse panels... under the hood and the instrument panel If you are sitting in the drivers seat it is above your left foot.
the turn signal flasher may be the problem moast vehickles have one forturn &one for 4way
the 4way mutil.switch. Headlights. turn sig. wiper washer. I was not the lcm.
behind the dashboard near the 4way switch just listen for a clicking noise when your taking the dash arpart and that is where you will find it im pretty sure im not a 100% on this
