Front driver side turn signal light doesn't flash.replaced bulb,replaced socket,all other lights work on emergency flasher,except front driver side.rear driver side turn signal light works,but flashes fast,also when turn signal switch is on for driver side turn signal,no indicator light on instrument panel.running light driver side front has power,just no flash.

The turn signal, brake light, and flasher are on the same wire. I would take a circuit tester light and trace the wire to see where you lose the voltage. It would likely be where two wire looms connect. I would look at the rear connector first.

Fast flashing usually indicates that one of the exterior bulbs isn't functioning. You've checked front and rear signal lights, right? If the bulb is good, it could be corrosion in the socket, bad ground, broken wire, etc.

Could be a wiring problem, or the turn signal switch.
You could check the wiring with a meter, and also by using the emergency flashers. Those use a different circuit from the turn signals on most cars. If the light works using the 4-way flashers, the problem is probably the turn signal switch.
You need to know if the socket has power and ground when the lamp should be flashing.

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.

You know you have 2 flashers right, one for emergency flashers and one for signal lights? Does it refuse to flash on both sides, right and left? Have you checked all bulbs front and back are good?

Check BackUp Module, generally is located in the rear quarter panel (drivers side).

Sounds like it's a problem in the turn signal switch. Are you sure you used the right bulbs when replacing them?

Yes all the wiring needs to be complete. Then all the bulbs must be inserted into sockets. left side marker right side front turn back turn reverse lights brake light everything. Then make sure they all work. The problem could even be a bulb thats on the fritz ready to blow but still on and dim little light. if that's all fine then it's probably your flasher. There are 2 flashers one for turn and one for hazards but I think they are the same but still separate. located under dash on either side of the steering wheel. The flasher closest to the door is up in there pretty far it's size is about like a 2 liter cap and it's silver. good luck

The quick flash is a fault detection for a burnt out bulb. If bulb is good, check bulb socket. Inspect for corrosion. If needed, replace bulb socket. Check bulb socket connector. Check if fuse. Check emergency flashers ( most cars have a separate circuit).
