Front left running light does not work, but flasher does
Have tried swapping out for new socket and tried 2 new bulbs. Both elements appear normal, but when lights turned on, the yellow running light does not come on, however, when the turn signal is activated, the other element does blink appropriately. Where could the problem be? Thanks

The flasher is under the dash.If you turn on the signal listen for it's location.Turn on your 4 way flasher and see if the left rear light is flashing.If it's not then replace the bulb.If it still does'nt work after replacing the bulb check if there is power to the socket. Use a probe light.If no power to the socket.There is a break in the wire or worse the signal switch may be the culprit
Has the vehicle been in an accident on the left rear side. First check the bulb to be sure it is not defective, trade it out with the side that works properly to test. If the bulb works well then My thought are you may have a shorted wire. The turn signal flasher works by heat build up within the flasher the heat is caused by the load of the bulbs, the load heats the metal spring causing it to open the circuit then as quickly as it cools down the circuit closes again lighting the bulbs.
There is also a possibility of a defect in the turn signal mechanism on the steering column. The turn signal switch on many models does three different things on many models that use the same bulb element / or bulb for brake and turn on rear of vehicle. It controls the circuit for brake light by sending power both left and right side rear when turn signal is in neutral position then when turn signal is in left turn the switch cancels brake light power to left side rear and supplies flasher power to left side while maintaining brake light supply to the right side rear, and so on opposite when the right turn is chosen on turn signal switch. The turn signal indicators on the dash normally run off the same circuit as front turn signal bulb only which is also controlled by turn signal switch. Front has turn signals but no brake light.
I think there is an additional load on the left side rear turn circuit and it could be either a wire that is shorted or the turn signal switch if the same bulb element is used for both functions.
Often times if trailer lighting is connected the flasher will also blink a little faster because of the extra load of additional bulbs.
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.
Normally, it means either the front or the rear bulb is burned out. If front and rear bulbs are good, and that means both lamp filaments in both bulbs are good. It could be the flasher, a bad ground, a bad bulb socket, or the turn signal switch.
No - headlight ok. The reason that the Right turn signal blinks fast is that there is half the normal load (resistance) on the right side, since the Right front turn signal isn't working. Since you replaced the Right front turn signal bulb, your problem lies in the bulb socket or the wiring to the socket. (1) try cleaning out the socket - there's probably a contact problem in the socket. You may need to squeeze the contacts together to provide good contact to the socket contact. (2) if contacts inside the socket are ok, try back-probing the socket - to make sure that the socket is getting 12V DC to light the bulb. Replacing a bulb socket is easy, and commonly done. Any auto parts dtore should be able to sell you a new socket - its just a matter of cutting out the old one, and then splicing in the new one. Most shops will use small wire nuts, buried under several wraps of E-tape (electrical tape). (3) if bulb AND socket ok, you have the worst problem known to man - a wiring fault. In this case, you'll want to run a new wire from the flasher module (under the dashboard) to the turn signal.
Maybe I'm missing something, but have you tried replacing the bulb? Sounds like you have a dual-element bulb, where the flasher (high intensity) element is out but the normal low-intensity element is still OK. Had the same thing happen on my Buick.
If you put a 2 element bulb in a single bulb elemet socket you would or could destroy the flasher unit. Especially if it is a electronic flasher try replaceing the flasher but get mechanicl flasher they last longer.
Usually when your signal blinks rapidly it indicates a blown bulb. Switch on your four-way flashers and check your bulbs at each corner. On the brake light staying lit, check to see if the left-rear bulb is installed correctly and is the correct bulb for the application. I've seen people force bulbs in sockets causing the braking element of the bulb to light instead of the parking element. The braking element is much brighter than the parking element.
