More than likely a bad flasher relay for the turn signals. The hazard lights use a different flasher relay.
how do you remove the turn signal assembly on a 1989 Pontiac Bonneville
You have a bad relay. Your blinkers run on a different relay than you hazards do.
Check fuse and/or flasher
you need to change the flasher can for the signal lights
The 1995 Pontiac Bonneville turn signal flasher relay switch can be found beneath the drivers side dashboard. The turn signal flasher relay switch will be above the accelerator pedal.
it is part of the hazzard light switch on the dash under the raido
Look for either a blown fuse or replace flasher unit for the signal lights (it is separate from the hazard lights flasher unit).
bad wiring in your steering column to the hand control?
The flasher on a 99 Bonneville is located under the dash below the steering column, remove the panel just below the column. It has screws.
Check the fuses
The turn signal flasher is combined with the hazzard switch. It is connected to the back of the hazzard switch.
When the signal lights are not working on a car, there are a couple of things that could be going on. One could be that the bulb needs to be replaced. The other possibility is that the signal relay needs to be replaced.
Both turn signals work when they want to. The hazzard lights work just fine. All bulbs are great. The turn signal indicator will flash inside the car for a few seconds and then stop. The outisde turn signal lights stop too.
Either there is a wire lose or the flasher relay is not working right or lose in its socket.
multi switch is bad
Check the left turn signal bulb. It is probably burnt out.
Did you change the bulb in the rear? Yes. The hazzard lights use the same bulbs in the rear as the turn signals. They work with the hazzards on but not with the turn signal.
signal lights not working.
We just had the same problem with a 2002 Pontiac Grand Prix. It turned out to be the turn signal/hazzard switch. Good Luck!
Try Replacing turn signal flasher
check the bulbs, the fuse..and then the flasher a manual will have a diagram See if your local library has a professional shop manual to look at for free... dave
Many mistake the hazzard flasher for the turn signal flasher. Maybe you replaced the hazzard flasher? Also, a burned out bulb will not give enough electrical resistance to the circuit, and result in a very slow or stopped flash. Since your flasher is most likely mechanical, turn on your hazzards and put your fingers over the flasher unit. If you feel it click on & off, then you need to find the turn signal flasher.. because you are touching the hazzard flasher.
May be a problem with the switch in the steering column
The front or rear turn signal flasher bulb may be burned out and needs to be replaced. The turn signal flasher my be defective and should be replaced. The hazzard lights have a flasher unit of their own. These are found up in under the dash in the steering column area.
Pulling the turn signal switch toward you should switch the lights to the low beams. If that doesn't work, you may have to replace the switch, which means replacing the entire turn signal stalk.
