Turn signal and headlights wired together

I have to keep my headlights on in order for my turn signals to work at all. If the headlights are turned off then it is as if I have not even switched them on, the hazards won't work either. Also I just found out that mu headlights are hooked directly to the battery. any Idea on how to fix this?

"...headlights are hooked directly to the battery" suggests that a previous owner had issues and wired it that way.
The solution is put the circuit (not necessarily the original wiring) back to the factory state.

What's probably happened is a bad ground for the headlight assemblies somewhere. It may also be that a short developed in the wiring harness, a not uncommon problem with many makes.

What you (or your mechanic) need is the schematic to
a) disconnect the previous owner's work; then
b) trace the headlight/signal control circuits though the relays to the headlights and signals; then
c) rebuild / repair as needed.

This can be a lengthy process, be prepared to pay forthe work.

Yes these switches can go bad. If it looks bad replace it. I have had switches like this do the same thing after several years of use.

SOURCE: My turn signals dont work

Did the battery get changed recently? There is a small black box under dash near steering colom that has a little red button on it. Press the little button for a few secounds allowing it to reset the security system. It should stop your marker lights from flashing. It was a stock security for that year. The box is about 4 inch square and is usually just under dash near your knee. Good luck.

SOURCE: 1999 subaru legacy. right front turn light

I believe you are correct. Whenever lights start doing goofy things like that it is almost ALWAYS a ground problem. I can help you. I can tell you EXACTLY where your turn signal and headlamps are grounded. However, There is one small problem. Subaru got STUCK on the "Legacy" nameplate. There are ten different Legacy models listed for the 1999 model year. If you can tell me which Legacy model you own, I can look up the wiring diagrams for your vehicle and provide the information you need. The choices are as follows:
Legacy Brighton Wagon AWD
Legacy GT LTD Sedan AWD
Legacy GT Sedan AWD
Legacy GT Wagon AWD
Legacy L Sedan AWD
Legacy L Wagon AWD
Legacy Outback AWD
Legacy Outback Limited AWD
Legacy Sport Utility AWD
Legacy Sport Utility LTD AWD

Just post a "comment" to let me know which one it is and I will post the information back to you.

SOURCE: Hi, I have a Subaru Legacy

It sounds like a bad alternator. How do you know the battery is good? Try to jump start it.

Testimonial: "I will try to do that! You might be right about the alternator, when I gazed it up all the lights lit back on normally and it didn't seem to be diying"

Why does my front right turn signal on my 2006 Pontiac Montana not work when the headlights are on?

What does the rear turn signal do? If one of the signal lights are not working, the other will blink faster. With the headlights off the turn signal bulbs ground through the light holder. With the headlights on the running lights are using the same ground circuit. Make sure all bulbs are good with a good ground.

Why only left turning signal not blinking only when headlights on? green arrow pointing left seen but not blinking. When headlights off, both turning signals work perfectly,

It sounds as though you have a wiring problem around that particular light/signal.

Check the black earth leads to the light and the signal - it may be nothing more than a 'bad earth' due to corrosion where the earth wire connects to metal.

Check the main power wires, too. It should be an easy fix .. make sure the wires are clean and secure

Problem with turn signal when headlight is on

this sounds like a earthing problem , so check the wiring for the head lights, see if any wires are trapped between something, bare wire touching car body , anythingthat doesn't look correct, could also be the indicator lever itself with a problem , but check the headlight wiring first

Left turn signal pops fuse on infiniti

Check front and rear lights to see if the wiring is arcing to the turn signal on the left side of the car. This is the best guess as it's simply a wiring problem and nothing else, as there is too much current being forced through the turn signal when the headlights are on. Headlights draw much higher current than the intermittant turn signals and therefore pops the fuse.

Headlights won't come on with switch but, will with turn on with turn signal and no tail lights fuses are all ok. does this car have a body modual for the lights and where is it located

You might need a headlight switch, also possible that you have a wiring problem, i would start checking the the condition of the wiring going to the lights to make sure they havent been compromised or have corrsion in them. Possible ground problem also. If the switch is a combination switch where the headlights,and turn signals are all together on column, most likely just replace that lever/turn signal switch.

Driver side signals only work when headlights are OFF

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.

Turn signals

You need to check the wires coming from the headlight switch. Also if you have a pug on the back for a trailer check it also. I have seen in the past wires that melted together from a short and it causes circuits to connect and work together.

Tail Light Malfunction

Try looking for the spot where all your wires come together, near the rear bumper. I was having the same issues until I found the problem today and fixed it. I found a loose ground to the frame the bolt holding multiple grounds was loose. I found it near the rear bumper. I tightened it up and everything started working correctly. Good luck, hope you can find the problem.
