My driver side blinker doesn't work Yet both bulbs in the fixture light up when you turn the lights on. I dont have a book on the car to match fuses with numbers so I was hoping for some help so that I dont have to go back to the factory

check rear driver light bulb see if its working that can effect it

replace the left blinker relay, located in the fuse panel.

TEST FRONT RIGHT BLINKER CIRCUIT AND REPLACE THE BULB,,WITH PROPER BULB...A DOUBLE CIRCUIT BULB IN A SINGLE SOCKET WILL DO THAT ALSO A SINGLE SOCKET BULB IN A DOUBLE SOCKET HOLDER....CHECK LEFT SIDE BULB FOR ACURANCY

it is in the flasher switch for hazards

when you use the right turn signal, does it blink faster?. Could it be the bulb holder is damaged or rusty?

It's the bulb. There are two filliments in the bulb. One is for when you turn your lights on and the other is for breaking and blinker flashing. When the break filliment goes bad it causes the blinker to flash very rapidly. 100% the bulb. Change it and all will be good again. P.S. if it were a fuse none of the break lights or blinkers would work.

It has a bad bulb. Find the bad bulb to fix this issue.

If the driver's side tail light is working, it's not a fuse. Use a test light to check for power at the bulb holder. One terminal will be for tail light, the other for brake/turn light. If the is constant power for tail light, replace bulb. If no power, trace wiring from bulb holder to driver's side junction. Probable broken wire between the two tail lights.

If you can turn the blinker on left or right and the light comes on but doesn't blink......Open the drivers door, there is a fuse box, On the side of the dash.. The relay willl be a small silver canister looking relay in with the fuses.. put your finger on it and turn the blinker on.. you should feel and hear a click...( With the key in the on position ).. That is what needed replaced if it doesn't keep clicking...Thats the turn signal relay... What makes it blink.......Hope this helps..
Please rate this solution if it helps... Thank You.....

Its one of your Relay switches.
