I looked this up and the manual leads me to think the problem is the electroinc flasher relay is the problem here, before you do replace it try cycling the turn signal switch quickly from left to right to clean the contact points of the switch, it may start working.
If you do need to replace the flasher it is located under the dash on the left (driver side) attached the same braket as the BCM (Body Control module), you will need to remove the filler panel around the steering column, that is the panel in front of your knees, also remove the panel on the bottom of the dash that is called the sound insulator or hush panel, the flasher looks like a relay it is plugged in on its side. I will show a picture of the flasher below, it is slightly larger than a standard Bosch type relay.

Turn signal and break light


Make sure all the bulbs are working in the turn signal. Some front turn signals will use two or more bulbs per side. If any one of these bulbs are burned out it will cause the turn signal to flash at a fast rate. It also could be a bad control lighting control switch a.k.a. multi-function switch.

03 chevy venture rt.front parking light&turn light don't work replace bulb&socket


The rapid flashing occurs because of the light problem. If the 20A PARK LP fuse in the underhood fuse block is OK, the front marker lamps and the park lights should turn on when you set the headlamp switch to PARK. If the 10A T/SIG fuse in the instrument panel fuse block is OK, and the ignition switch is on, moving the turn signal multi-function switch to signal a right or left turn should cause the turn signals to flash. If this doesn't happen, check for a missing ground connection to the socket you replaced and check to be sure the replacement lamp was not forced into the socket backwards (it happens).

Turn signals won't flash. They do come on but no intermittant flashing. Flasher has been swapped out. All turn signal lights come on on both sides front and back.


i think you may have replaced the hazard flasher not the turn signal flasher, the turn signal flasher is located behind the dash on the right side of the steering collum support, the hazard flasher is located in the convenience center.

Have a 99 suburban 4x4 , all three back brake lights do not wrk


I was having the exact same problem as my brake switch was fine on my 95 suburban. However upon further inspection the problem was very simple i felt really dumb once i found this: the wire harness that comes away from the switch witch is a bundle of white wires that comes down and across the under side of the steering column had 2 damaged wires upon repairing this i have had no problems since then feel free to email me on this problem at captainchicken08@hotmail.com as i will do my best to help u out. But the problem is most likely a wire short out, or damaged wires for the normally open circuitfor your brake switch.

Parking lights work third brake light works,just not back brakes?


The bulbs do not need to be replaced! The answer to this problem is believe it or not in the turn signal lever, or multi-function switch. It is extremely common on these cars, and usually mis-diagnosed. Try this before going any farther. Back the vehicle up to a wall, or have a person stand behind the car, and pull the turn signal lever slightly towards you as if you were switching between hi and low beams. I guarantee that when you put just a little pressure on the lever your brake lights will work. If you want the problem fixed, you need to have the switch (and lever arm) replaced from inside the steering column, and you need someone to remove the airbag to do this. The switch is roughly $200 from an aftermarket parts store. If you learn to drive your car and just know that when you brake you can pull back on the lever to make the lights work great, I did for a few years in mine. But I guarantee that is the answer to your problem

I have a 1999 buick regal ls dying.


I have a 99 Buick Regal and it too dies out, but only when I use my turn signals. Sometimes, when trying to start the car...the dash lights would flicker and you can hear some sort of electrical ticking sound. As of today, my car will not start (5/24/09) it hadn't turned over since yesterday. After a process of elimination and searching the net, I think I need a new ignition switch. You may need one as well.

Signal bulb on 2003 buick regal


To change front turn signal –
open the hood; look in back of headlight; two white clips; pull straight up, and then whole headlight comes out including turn signal; it is all one unit; remove rubber cover, then you take bulb out of unit. Mechanism that bulb fits in will need to be turned clockwise (looking from the front) and pulled to get it out of the larger unit holding all lights. Be sure and put rubber cover back on before re-inserting the two white clips.

Brake lights dont work, Turn Signals all goofy


First thing i would do is chg. the break light switch, and make sure to chk. all grounds around tailights, sometimes if there is a ground problem it will travel back thru the hot wire to get a ground, witch in turn makes everything go wackey.
