SOURCE: Left turn signal stops flashing when brake pedal is depressed.

there is a ground problem, most likely in the tail unit itself, but a ground problem is hard to find and easy to fix. reground the system, the turning unit, and the problem should stop. About the hazards, I don't know...... some times in older cars, that is the way it works. because the brake and hazard element in the bulb is the same and the old cars used a break in the power, but the new cars use a break in the ground. any way, chase the ground down first, it is usually the cause.

The hazard back lights wont quit blinking when car is running even when i pull the fuse on a 2002 buick regal


What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

I can't find the turn signal flashers on my 99 Olds delta 88 but I did find the emergency flasher. Does it have one or two flashers because my signal light are not working at all HELP PLEASE!!


One flasher only. Check fuses first. Then suspect the flasher as a possibility. I have seen the hazard switch cause the turn signals to malfunction. Try pressing the hazard button in. If they work and flash as hazards you know the bulbs and flasher are ok. If the turn signals then work you have a defective multifunction switch (the hazard/turn signal/etc switch)

1985 LeSabre flashers work turn signals don't need location of turn signal switch or are they one of the same


You mean turn signal flasher? No, the hazard flasher and turn flasher on older cars were separate. Often, the hazard flasher was right of the steering column (under the dash), and the turn flasher was left of the column. Look for two similar canisters. Turn the hazard lights on and locate the hazard flasher by feel or hearing. The turn flasher will be the other one. They both may be retained by metal clips.

Turn lights blink with hazards but not with turn signal..flasher replaced. is It the multifunction lever then??


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

2000 tacoma flashers don't work but turn sig do work!


The hazard switch gets power from the horn fuse which is hot all the time, and from the turn signal fuse which is hot when the key switch is on. The turn signal switch gets power from the hazard switch and both use the same flasher.
So if the turn signals work but the hazard switch does not power the lights, and both fuses have power, I would say the problem is inside the hazard switch.

Turn signals heater


Did all these problems happen all at one time?? If so you may have a bad body ground. Try running a electrical wire from the (-) negative side of the battery to the body and see if this works. Be sure this wire is to a place with no paint as low voltage electricity will not flow through paint.
A). If not try replacing the turn signal flasher for the turn signal problem. This is usually the culprit and it's easiest and cheapest to replace. The turn signal flasher will be found under the driver side dash next to the hazard flasher. Turn the hazard flasher one to locate it. If you want try swapping the turn signal flasher with the hazard flasher to see if this fixes it. They are the same style flasher.
If this doesn't work you may a faulty turn signal switch or some wiring issues.
B). It could as simple as the head lights bulbs need to be replaced, it's rare but I have seen when both bulbs blew at or near the same time. If your able check the voltage at the head sockets.
C). Could be a bad blower motor or switch. I'm not sure if these models have a resistor block or not. The resister block controls the electrical current going to blower motor which controls the speed of the blower fan.

Can a turn signel work for about 15 seconds and then stop? or could it be the relay?


the flasher unit is probably worn out.there is a bi-metalic metal strip that gets tired and won`t expand and contract making the clicking noise you hear when the signals are in use.it stops expanding and contracting causing the flashers to stop working.change the flasher unit but make sure you changing the one for the signal flasher and not the hazards flasher as they look the same.to know which one turn on the hazards and look for the other flasher that is not making a noise as this will be the one for the signals.
