I need help with a problem I am having with my left turn signal. I have a stock, for the time being, 1992 240SX Coupe. My left turn signal is blinking faster then the right turn signal, which blinks at the regular speed. Also my rear left turn signal does not blink at all, I checked the bulb and it's not bad. The right front and rear turn signals blink regularly. The problem is with the left side only. I checked the fuses in the car and in the engine bay and everything looks okay. When I put the hazards on, both sides blink at the regular speed, but the left rear turn signal still does not blink at all.
I cannot really think of what maybe causing it.

If anyone can help it will be greatly appreciated
