There are many problems that come with owning a car. If a Left rear brake and turn signal do not work, a person should check the fuses, bulbs and wiring.
Bulb is out.
Hand signal: put your arm straight out of your left hand window and fix the light before a cop sees it
Did you change the bulb in the rear? Yes. The hazzard lights use the same bulbs in the rear as the turn signals. They work with the hazzards on but not with the turn signal.
Check the ground wire and the light socket for the left turn signal bulbs (front and rear). You might be getting a ground loop.
1989 silverado left turn signal set applying brakes causes the left turn signal to dim and the two right rear tail light bulbs to alternate brightly? Further problem occurs to same truck - in Park and brakes not applied -- if head lights are on turn signal flash slows right down almost to a stop and becomes very dim
It sounds like you have a turn signal bulb out probably the left rear.
You may have a "ground loop" problem on the left turn signal. Check the ground wire at the front and rear signal bulbs.
replace bulb in front
The turn signal and brake light use the same bulb. When you get a fast flash, it is from a reduced electrical load being placed on the flasher unit due to a burned bulb. Replace the bulb and this should fix your problem.
It turns out the problem was that a couple of bulbs on the left side were burned out (front left turn signal, one of the rear turn signal/brake light bulbs.) After replacing the rear bulbs, the signal would work, albeit slowly. Once I pulled the front left turn bulb (with the intent of replacing it the next day), the turn signal light went steady-on regardless even without moving the signal indicator arm. That problem also went away when the remaining bad bulb was replaced.
Replacing the non-working bulb for left turn should resolve the problem and it will stop the cops from pulling you over too.
