What happens when you turn on the hazard switch?
Once the switch is on, the voltage going through the flasher heats it up and eventually breaks the circuit, turning the switch off until it cools. Once it cools, the circuit closes again, turning the switch back on.
Is there a problem with the turn signal hazard relay?
While issues with the turn signal hazard relay will not normally affect the driveability of the vehicle, they can cause problems that can compromise vehicle visibility and safety. While flasher relays are not complicated components, they can sometimes be difficult to diagnose due to the highly complicated nature of electrical systems.
Why does my blinker keep clicking when the turn signal is off?
It turned out to be a failing multifunction switch (turn signal, cruise control, wipers, etc). It’s a known problem with GM vehicles of this era. Try spraying some CRC Electrical Contact Cleaner into the base of the switch at the steering column to clean the switch contacts.
What are the symptoms of a bad turn signal Flasher?
1. Turn signals or hazards do not function. The most common symptom of a bad or failing turn signal / hazard flasher is hazards or turn signal lights that do not function. If the flasher breaks or has any internal issues it can cause the lights to malfunction, or not respond at all when the turn signal lever or hazard light button are pressed.

Why does my ASD keep clicking on and off?
The main computer board cracks, and it causes the ASD and fuel pump to click on and off constantly. Locate the problem relay. Open the lid on your fuse box and take a look at the relays — the small black cubes scattered around the fuse box.
What happens if you Jiggle the turn indicator?
Jiggling the turn indicator has no effect. Until a replacement owner’s manual is acquired, the car’s owner does not know how to replace the thermal oscillator. Without a wiring diagram, I have been unable to imagine a failure that would account for the symptoms.
Why is my Fuse Box making a clicking noise?
This can be caused by a computer failure, resistance in the ground wire for the control side of the relay or high resistance in the power supply to the control side of the relay. To find out the source of the problem, you’ll need to run some quick tests using a multimeter.
