In these newer cars they have installed separate fuses one for each side see if that is the case, if it is problem solved. If not you will need to check the line with a meter to see if you have any power going to the light area . If that's the case hook a hot lead of the turn signal and trace it backwards. Have you also changed the flasher unit. If not try it.

Turn Signal Lamps
The LT T/SIG and RT T/SIG fuses located in the underhood fuse block supplies battery positive voltage to the body control module (BCM) for turn signal and hazard lamp operation. When the turn signal switch is place in either the LEFT or RIGHT position, ground from G202 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. The BCM also sends a message via GMLAN to the instrument panel cluster (IPC) to cycle the turn signal indicator ON and OFF depending on the position of the turn signal switch.
Ground for the turn signal lamps is supplied as follows:
• G101 provides ground for the left front turn signal lamp
• G100 provides ground for the right front turn signal lamp
• G302 provides ground for the left and right rear turn signal lamps

The LT T/SIG and RT T/SIG fuses located in the underhood fuse block are also used by the body control module (BCM) for stop lamp operation.
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The body control module (BCM) provides both, a 5-volt reference voltage and low reference to the brake pedal position sensor. The position sensor provides an analog voltage signal back to the BCM that will increase as the brake pedal is applied. When the brake pedal is applied, the BCM will then apply battery voltage to the left and right stop lamp supply voltage circuits and the center high mounted stop lamp (CHMSL) supply voltage circuit illuminating the stop lamps. At the same time the BCM signals the transmission control module (TCM) and the engine control module (ECM) that the brakes are applied. Ground for all stop lamps is provided at G302.
The stop lamps on this vehicle will not illuminate unless the ignition is in the accessory, run, or crank positions. When the ignition is in the OFF position the stop lamps will not illuminate when the brake pedal is applied.

Did you check the fuse's. ? Wouldn't think it's a ground because right an left tail lamp Assembly's use same ground ! Did you check for B+ voltage at the bulb. with a volt meter ? Power is supplied by the BCM . Could be the tail lamp assembly

Where is the Hazard/Turn Signal Module Located


Hi. Turn the blinker on and feel your way down to the flasher unit. You will be able to feel it when it is clicking. Replace that unit and that should fix it. Good luck.

My 97 chevy blazer, the brake lights dont work but the third brake light does and the turn signals or hazard lights dont work??


More likely it is the hazard/turnsignal/highbeam/cruise control switch module. It costs about $275 for the module. However there is a repair kit for the likely culprit...the hazard button. Try jiggling it around a little, see if that helps. Spray a little WD-40 into it so it can jostle back into it's correct position. You could try a junkyard unit or Ebay. It's not too hard to change. The hard part is doing it without removing the steering wheel. It can be done. I've done it. But hopefully you can locate the repair kit which costs about 15 dollars. Good luck.

My turn signals and brake lights are not working (97 GMC Suburban). reverse lights work fine. it is not a bulb problem i tried to change them. one of the circut boards for the lights is new. not sure if...


Does your high mount stop light work? If it doesn't, then it'll be the brake switch located just above your brake pedal.

If the light does work, then it should be the electronic flasher module that will be located under your dash near the steering column. It will be labeled. This controls your signals, but I believe your brake lights are also on the same bulb as your signals, so when this goes, it can affect your brake lights

Left turn signal light flashes very fast and does not make the left rear taillight blink. I replaced the turn signal relay but still have same problem. Fuses checked out okay.


Change the left rear turn signal light bulb. It is probably burnt out! The fast blinking flasher is the clue you have a blown bulb.

Turn signal not working


on an older car this woul dsimply mean that the turn signal flasher was burned out for that side. today its more complex. the turn signal flasher is a series of resistors and timer modules located in the workings of the body control module. This can be a simple problem with a shorted line, or a faultly turn switch or something as complex as needing a new body control module. This is something that needs to be repaired by a quality automotive mechnican with an electrical backround, and unfortunatley unless your in the nyc area i have none to suggest to you.
