Turn Signal dont blink hazards flashers work no 2001 Chevrolet Venture

Generally speaking, symptoms of a bad or failing turn signal bulb are usually the culprit...in your case, either it's the front left or rear bulb. Varies for different vehicle makes...common signs include:

1. turn signal light staying on solid
2. or blinking very fast
3. or either sides of the bulbs stop blinking altogether.

To test this, make sure you reconnect everything you disconnected.
Turn the left signal light on; go to the front of the vehicle, is the turn signal bulb illuminated? If it lights up, even though it is not blinking obviously the bulb is okay. If it doesn't, replace it- problem solved. You'll do the same procedure for the rear turn signal Is that lit up? If not replace the bulb and the problem is solved.
Another common failure is when the turn signal blinks really fast, same procedure as mentioned above.
If both bulbs for the left side and right side illuminate but don't blink, the problem is in the steering column turn signal switch.
If the left or right side blinkers don't work properly at all...then check the integrated hazard warning/turn signal flasher relay- that may be defective; again, that's usually the case if both sides of the signal light don't work.
If you are blowing any fuses related to the flasher system, you have an electrical overload in the turn signal circuitry.

There should be a turn signal flasher and a hazard flasher. They are two different parts. If you replaced the hazard flasher and not the turn signal flasher than I would start by replacing the turn signal flasher.

One thing you can do once you find the turn signal flasher is to unplug it and use a jumper wire between the two pins of the connector then turn the key to the run position and place the turn signal lever in the left or right position. If the turn signal lights know light up than the turn signal flasher is the problem

The first place to start are fuses, check your owners manual for location, typically left side of dash.

The emergency (hazard) flashers and turn signals are on separate fuses and run through the hazard switch. If all the lights work when the hazard switch is on then the problem will likely be a blown turn signal fuse.

Other possibilities are the hazard switch itself is bad, the turn signal switch is bad or a broken wire, all of which require a meter (or test light) wiring diagram and knowledge of the circuit to test it - better to have it done.

The easiest thing for you to do would be to replace the bulbs that are on that circuit. You should have one or two bulbs with a double filament, one for the brake and turn signal and one for the tail light.
If that does not fix the problem, someone will need to check the circuit for power from the turn signal switch. It takes all of the lights on one side to make the turn signal flash.

Your vehicle has 2 flasher relays. One for the turn signals and one for the hazard lights. The turn signal flasher relay is located on the drivers side, under the dash, mounted on the drivers (Left) side of the steering column. The hazard flasher is mounted on top of the steering column. Do not get them mixed up.

you could have a bad flasher unit causing this.you say hazard/flasher not working.do you mean just the signals not working and think the hazards won`t work or are the hazards not working.there are two flasher units one for signal and one for hazards.you could have a problem with the signal switch as well.

you don`t say but do the lights work either on the front/back on both sides.if not then it may be a fuse that needs replacing or need a bulb replacement.if the lights work but don`t flash then it sounds like a signal flasher problem.the flasher is located in the fuse panel under the dash on the drivers side.if the hazard flashers work then turn them on to find the hazard flasher by the fuse panel then you will know what the signal flasher looks like and change the signal flasher.make sure you change the one for the signals and not the hazard one.if the hazards work then i would say the signal switch is good as the hazards work through the same switch.

Probably the flasher, as I think you have a separate flasher for the turn signals under the dash above the brake pedal. It is probably next to the hazard flasher. If you can't find it, turn the hazards on and follow the sound. The turn flasher is probably next to the hazard flasher. Please let me know if this isn't the problem or you have more questions.

It should be in the hazard button, You have to pull it out and replace it. Try the junk yards they dont cost alot.
