Start by checking the fuse under the dash panel. And make sure your bulbs are good. If nothing happens at all when you use the turn signal switch, it is possible you have a bad flasher relay located under the dash, the little cylindrical unit that causes turn signals to blink, and makes the clicking sound when signals are blinking. Used to be very cheap, but the newer units are a little more pricey, more sophisticated. If a new flasher doesn't fix it, then you may have a bad turn signal switch on the steering column.
The circuit for the turns goes from the fuse, up to the turn switch, back out to the flasher, and then to the turn signal bulbs.
Good luck.

I have a 2001 Pontiac Montana and none of my lights in the back work . I dont know.what it may be and dont know how to fix plz help.


If none of the lights in back work, it sounds like something happened to the main wiring harness. Which is probably beyond your ability to repair at home.
If the parking lights and turn signals work in front you know the fuses are good, so they should also work in back.
The parking lights, turn signals, back up lights and brake lights are on 4 different circuits.

I suspect there is a problem with the turn signal/ hazard switch. turn the turn signal on left or right, if it doesn't flash, grip the hazard button and gently wiggle it around, if the signals start flashing, replace the turn signal switch. The Brake lights are wired through the turn signal switch, if the 3rd brake light works, the brake switch is OK. I don't think it has anything to do with the anti theft system (at this time)

1993 Geo Prizm turn signals dont work. Hazard lights DO work. Checked fuse several times & its ok. Any suggestions?


You have a bad turn signal switch if the hazards work and the turn signals do not. It has nothing to do with the fuse or the flasher unit. Your switch is bad or you have a bad connection some where.

Chevy Cobalt turn signal issues


There is a plastic piece inside the steering column that will automatically turn the turn signals off when the steering wheel is turned back to 'straight ahead'. This plastic piece can break, and if it does, they can only be turned off manually, as you are doing. I have not worked on anything as new as your cobalt to repair this, but on older cars it involves removing the steering wheel and turn signal assembly. You must also deal with the air bag. Don't attempt this repair unless you have a manual to follow to disarm the air bag and properly remove the steering wheel and other components.

I have a 92 lumina. The turn signals dont work.


The hazard lights has it's own flasher, change the flasher for the turn signals and see if that works. To find out which flasher it is, put on the hazard lights, and put your finger on the flashers, which ever one you don't feel clicking is the turn signal one.

If the turn signal is stuck in the position,then the turn signal switch is bad,now if the turn signal just stays on,and does not blink,and the turn signal lever returns to the neutral position,then it is a bulb that is bad on that side on the car,,front,side,or rear.If the turn signal moves to the left position,and returns back to the neutral position,it is ok,unless it is blinking,then it would be bad,the turn signal switch.

Turn signals are not working only emergency


It sounds as if the turn signal flassher relay has failed, common for these to fail with time. I'd take it by a good auto supply shop they'll get you the correct part and should be able to locate the unit for you too. If this is the case it should be @ $5-$10 to repair.
I hope this may have helped,

Flash signal


Hi,

To my knowledge the turn signal flasher for a 2001 Oldsmobile Alero is part of the Hazard Flashing switch. It is actually a 4 way flasher unit in one assembly.

Additionally, there was a recall order for 1999-2002 Alero models due to electrical issues which includes signal lights. You can try calling Oldsmobile at 1-800-630-6537. The Ref. No. is 04098A issued Jan. 11, 2006. Accordingly, the repairs will be made at no charge to the customer. The special policy covers warranty repair (for such problems) for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
