2001 Olds Aurora Hazard lights don't work. Indicator on hazard light switch illuminates. Signal lights are functioning properly.

The direction indicators are unlikely to work correctly until the hazard light switch functions correctly - the hazard switch is usually wired so when operated it has cut the direction indicator wiring and connected itself to the lamps rendering the direction indicator switch redundant.

Lots of cars suffer indicator problems when the hazard switch is rarely used. Often a few minutes vigorously operating the hazard switch restores operation but if the switch is broken it must first be replaced.

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.

Turn Signal Lamps
The turn signal lamps may only be activated with the ignition switch in RUN or BULB TEST position. The T/SIG fuse supplies ignition voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, the turn signal switch sends an ignition voltage to the hazard lamp/turn signal flasher, which sends an on-off signal to the turn signal switch. When the turn signal switch receives the on-off signal it will send that signal to the following lamps on the LH or RH side:
?€¢
The Rear Turn Lamp

?€¢
The Turn Signal Indicator

?€¢
The Sidemarker Lamp

?€¢
The Sideview Mirror (Pontiac Thunder only)

The turn signal switch also sends a separate on-off signal to the Daytime Running Lamps (DRL) control module, which relays the signal to the appropriate front turn signal. The front turn signals are grounded at G101 and G102. The rear turn signals are grounded at G401. The sidemarker lamps are grounded through the corresponding front parklamp.
The sideview mirror turn signals are a bank of LEDs placed behind the mirror glass.
The hazard lamps operate on battery voltage. The HAZARD fuse supplies battery voltage to the turn signal switch. When the hazard switch is pressed, the turn signal switch sends battery voltage to the hazard lamp/turn signal flasher, which sends an on-off signal to the turn signal switch. The turn signal switch send the on-off signal to all the turn signal lamps, causing all the lamps to flash including both IPC turn signal indicators. The hazard lamp/turn signal flasher is grounded at G200.
When the parklamps are ON, the sidemarker lamps receive voltage from the park lamp supply voltage circuit and illuminate. The sidemarker lamp is grounded through the corresponding rear turn signal. When the turn signal switch is place in the left or right hand position, the rear turn signal illuminates and the sidemarker lamp will loose its ground, causing the sidemarker lamp to turn off when the turn signals are on and to illuminate again when the turn signal is off.
Which blub an socket did you replace ? check the other blub ? The switch and or the flasher module can cause this problem .
Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column.
Did you complete the replacement?

Which

I suspect that the problem is in the indicator switch and not the lights. To prove this press the hazard lights and if all lights flash it is not the lights or circuits./he indicator unit just flashes and the power is directed to each side depending on where the indicator switch is positioned . If one side flashes first and repositioned to the other side and it won't work then it indicates a switch fault and not bulbs.

YOU MIGHT HAVE A BURNT OUT RELAY IN FUSE COMPART UNDER YOU CARS HOOD CHECK THAT OUT THRU YOUR CARS MANUAL,IT WILL SHOW YOU WHICH RELAY IT IS?

There are TSB's for this issue. I chased this issue for months on mine. Go find the TSB's, there's troubleshooting pointing out the faulty part. It could be, the brake light switch, the hazzard light switch itself, the multi-function switch. I had replaced all of these and still had the problem. Wiring that goes from the brake switch to up near the fender was shorting against the fender. I replaced the pigtail, problem fixed. Best bet to help you, is find the TSB's for this problem.

MOST OF THE TIME THE SWITCH BRAKES IN THE STEERING WHEEL CONSIDERING IT JUST A SMALL PEICE OF PLASTIC.

It is absolutely possible, and recalls are free. Take the free recall and hope it solves your issue!

There are two seperate circuits in operation here and therefore two fuses to be checked ! If all checks out you can turn your attention to the hazard switch on the dash,. The indicator circuit is connected thru the hazard switch for safety reasons nad it's dependant on a closed circuit connection thru the hazard sw to function properly ! Bad connection maybe as a result of prior disturbance oc connectors ? Good luck

I have the same issue. There appears to be a bad harness connection, short term fix is to adjust the wheel up rather than down and see if that helps. You can take apart the steering assembly and see when the tension of moving the steering wheel down causes the connection to fail.
