A bad ground circuit will present a power to ground situtation. This will keep a light lit. Check all grounds in the problem area
Good luck

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.

My driver side taillight won't stay on. It can blink when I signal or have my hazard lights on but they won't stay on. Mechanic replaced the lights about two or three times but still no. Any ideas?


Could be a bad ground connection.
The ground could be too weak to carry voltage for the tail lamp circuit and the turn signal too.
The tail lamp and turn signal are two separate circuits.

2005 ford focus zx4. No brake lights, turn signals or hazards. Fuse doesn't look like it's blown. HELP


Hi Sue:
I'd suggest using a voltmeter and start checking at the supply side of the fuse. AS these are all on the same circuit there's a failure at ome point so working "downstream" until you don't have power will ultimately locate the problem component.
Also, was anything done that might have caused the problem?
Re-phrased, At some point, they worked properly. What happened right before they stopped working?
It might lead you to the source of the problem.

Turn signal lights don't work


The first place to start are fuses, check your owners manual for location, typically left side of dash.

The emergency (hazard) flashers and turn signals are on separate fuses and run through the hazard switch. If all the lights work when the hazard switch is on then the problem will likely be a blown turn signal fuse.

Other possibilities are the hazard switch itself is bad, the turn signal switch is bad or a broken wire, all of which require a meter (or test light) wiring diagram and knowledge of the circuit to test it - better to have it done.

Turn signals and brake lights will not work


A mechanic would check for voltage at the multi-function switch in the column. Those three circuits go thru the turn signal switch.

The turn signals and hazard flasher should be on two different circuits, so I doubt a fuse would be the problem.
The multi-function switch in the column is the only thing I know of that would affect both.
A mechanic would test the circuits at the harness plug.

My hazard lights won't come on at all. The turn signals work fine, as long as the hazard button is not depressed. The hazards used to work, but if the hazard button was pressed and I put on a turn signal,...


sounds like a dirty switch, happens a lot in the UK as the switch is checked for the safety every year so the dirt in the switch causes open circuits, it is a complicated switch, it has many contacts that do different things when in and out, try a salvage yard

1992 Ford Ranger Turn signal/Hazard light issue


Can you just check to make sure the ignition key switch is not staying over to far and not backing off when you try to start it. I had a truck that did that and it messed up my turn signals until I brought the key switch back a little after starting it. Just a simple idea. Be kind with your rating for me. Raz

2002 chevrolet cavalier, my brake lights, front and rear turn signals and hazard lights are not working


Your Hazard switch is bad. There were a bunch that had faulty soldering connections, and would fail prematurely. This circuit also competes with the turn signals, and the brake lights. Replace the switch with an aftermarket replacement, and it should fix your issue.

Turn signal lights are staying on when key is out of ignition


This one can be tricky. Cause may be a defective hazard relay, or the BCM (Body Control Module) has an internal malfunction. You'll want to ISOLATE both of them. You cannot disconnect the hazard relay as it is an 'integral' part of the BCM. You'll need to disconnect BCM connectors BCM-CE, -FF, & -IM to verify if the problem is inside the BCM.

Since an internal short is suspected inside the BCM, verification of this is done by disconnected these connectors one-by-one and watch the results (each turnsignal lamp with go 'OFF" when its ground circuit is removed.
