Turn signal/hazard light inoperable---left front only
I tried a new bulb and it did not correct the situation. The bulb does work when the headlights are turned on. The left turn signal indicator goes solid green in the instrument panel as well as the rear turn light, but the front left is a no-go. Is there a relay or module in the system somewhere for the individual lights? I played with the hazard & turn signal fuses and they appeared to be okay.
Re: Turn signal/hazard light inoperable---left front only
I recommend replacing the pig tail that holds the burnt signal bulb. These tails are available at most auto parts stores for about $10. Coat the contacts for the bulb in dielectric grease to prevent reccurance. I have done this several times, cheap, quick and easy. This is a very common problem on F-bodies, just take note as you see them driving at you on the highway with one DRL on and one off. Good luck.

I don't believe it would be a bad ground for just one light. It could be a wire, a socket connector, or the bulb socket itself. See if the wire has power at the socket when signaling left, with key on. If there is power, probably a bad socket or connector. If no power, check for power coming from flasher-the wire going to front left, or driver's side. If you have power from the flasher, but nothing at the socket, the wire has probably broken. Good luck.
mporteous, It sounds like you have a light switch problem. I can't think of any other reason for the running lights and tail lights not working in this situation. Are your brake lights working when the headlights are off and how about when they are on? Do your four ways hazard lights work in these situations? Try all the lights under these conditions. The reason the left turn signal blinks very fast is because one of the bulbs are burned out. Try the left signal and one light (front or back) will stay on and the other will not come on at all. Replace the bulb that does nothing. Do this before you try all the lights in different situations. I think that you will have to replace the light switch. Good luck with this.
The rear left turn signal bulb must be replaced immediatly before it melts the light socket, if it has'nt yet. Also please verify that the correct light bulb is being installed. because even though many bulbs look the same they are not identical. Installing the wrong bulb can be the begining of many, many problems in the particular circuit
Ok. First of all, chk all the bulbs. Well at least the four parking lamps. The ones that are supposed to flash. One or two are burnd out. It happens. The flasher(s) work on resistance and that is provided by the bulbs.Brake likes and the turn signals are electrically associated.and you already said one side does not work, so let's start with bulb inspection Let me know
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.
I had the same problem with a 960. I checked the rear turn signal bulbs and they were okay. I took a look at the front left turn signal bulb and the two contacts on the bottom of the bulb had melted into one contact. If you remove the bulb, the turn signal will function again when the parking or headlights are turned on, but will flash fast since there is no bulb in the socket. You may also want to check the socket of the bulb to be sure that they are not shorted together.
