Sound like either a bad wire or some have a fusible link that can go bad.
A faulty hazard switch which also has a built in relay like the turn signal, can cause problems as well.

Alpha Romeo 156 My Left hand indicator light stays on continually, does not flash. and when I turn the hazard light switch on both indicators continually glow.


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.

!997 Ford Thuderbird brake lights and hazards do not work


Lets start at the beginning.
The turn signals and brake lights use different fuses but both go thru the turn signal switch and use the same bulbs.
Have you checked the fuses for each circuit and does each switch have power in and out ?

I need to find the flasher relay for a grand marquis 2001 .does it has one? My turn signals wont work I can hear the sound but don't even flash


Yes, it does have a flasher, although it may be a combined unit with the hazard flashers relay. So you hear the clicking of the flasher relay? That seems to indicate the relay is working properly. Have you checked the bulbs and the turn signal fuse? Any turn signal bulbs light up anywhere, front or back?
How about your brake lights, do they work? Your car may have separate, stand alone turn signals in the rear, but many American cars use the same bulb and same filament on the bulb for the brake lights and turn signals. If your merc is like this and the brake lights work, then the bulb must be good.
Turn on the hazard flashers and see if all bulbs work and flash at each corner of the car. This would be the same bulb as for the turn signals. If they work, it could be a bad turn signal switch, may even be the flasher relay somehow malfunctioning, and in a few cases, a bad hazard switch can affect the turn signal switch. Check fuses and bulbs first. If you have any type of body control module that controls lights and other accessories, you may have to investigate that. I know I'm not being very helpful, just throwing out a few suggestions. Good luck.

I have no signals and when brakes lights are on, lose brake light to either side turn signal is set on


Hi!!

If you activate the turn signal switch and you step on the brake pedal, the turn switch (on the steering column) deactivates the brake light to make the signal light more visible. The bulb for the stop and turn lights is the same.

Turn hazard lights ON. If they don't blink, replace turn/hazard flasher, If one or more lights don't come on, replace bulb.

Check fuse and circuit wiring for broken or loose connections. If all looks fine, check following:

If front turn lights work fine, check brake/turn bulbs.

If turn lights come on but don't blink, replace turn signal/hazard flasher.

If front and back turn lights don't come on, replace switch on column.

Let me know how it worked out, Good Luck

I have brake lights and hazard lights. i do not have turn signals. in dash indicators for hazard lights come on, not for turn signals. fuses look fine and i found 1 signal bulb in the rear that needed...


If the fuse is ok then I would look into replacing the turn signal switch. This is not a very difficult task at all. If you have the hazards then your flasher unit would be ok. If there is only one bulb out then you are probably looking at the switch.

No turn signals, no tail lights and fuses are good


Replace the non-working tail light bulb. Try replacing the bulbs for the turn signals. If that doesn't work, replace the relay.
