Left rear tail lights/ blinker will not come on

There should two separate bulbs for marker and blinker. It sounds like a bulb is burnt out, bad ground, melted socket or a wiring anomaly. Are you certain it's supposed to have 57 series dual element bulbs for blinker and markers?

Your right rear turn signal bulb is blown.Replace the bulb and the fast blinking will stop.

REPLACE THE TURN SIGNAL BULB THAT DONT BLINK.MOST OF THE TIME IT IS THE ONE NEED REPLACING.

could be the tail lite housing. or the ground on the frame rail back near that location. remove the assembly till its hanging by its wires and remove the bulb. using a test lite probe the socket with the flasher on see if it blinks. if not go down under the rear of the truck and unplug the connector for both tail lites and do the same probe each connector on the harness that goes forward till your test lite starts to blink if it does there then the tail lite assembly is bad if not then repost and ill lead you further

Usually a fast flashing signal is because one of the bulbs is burned out or shorted out. If the signal and brakes use the same light which many cars do then check the wiring to it and replace bulb. If burns out again then it has a short between the signal switch and the actual light or the brake wiring to it is shorted.

the fuse is broke

IT WAS THE TAIL LIGHT BULB

THANKS

NO PROBLEM TURN ON THE RIGHT BLINKER THEN WALK AROUND THE CAR MAKE SURE FRONT AND REAR BULBS ARE FLASHING... IF YOU HAVE A BULB OUT YOU WILL NOT OFFER ENOUGH OF A LOAD TO THE FLASHER... WILL CAUSE IT TO FLASH FAST... IF OK THEN MAKE SURE THE PROPER BULB NUMBER ON BULBS AND MAKE SURE CORRECT BULBS USED IN VEHICLE.... IF OK CHANGE FLASHER

Using a test light check to see if there is power to the wire at the plug where the bulb is for the blinker. if so the socket is bad. if not check to see if the light assembly is working for ex. the parking lights or the brake light ect If those lights dont work then check the fuse for the right rear tail light. Hope this helps.

Usually a fast turn signal means that there is a light out. You should probably check all of your lights, including back-up lights, and turn signals. If there is one out then replacing the burnt out bulb should fix the problem.
