Q: My rear left turn signal will not work and I have replaced the bulb and checked the fuse.

asked by on September 09, 2016

In my audi, my rear left turn signal does not work. The front left and both signals on the right side all work. The front left blinks faster in oder to compensate. I have replaced the bulb but that did not work. I checked the fuse and they are all fine. I checked the socket and it looks clean. I am not sure what else to do.
My car has an automatic transmission.

Hey there. The most likely problem is the bulb holder / socket itself. It may look fine but probably has a crack or break internally. Also possible (but rare) is the circuit board within the tail lamp housing itself. I recommend having a qualified professional, like one from YourMechanic, inspect the lights in person in order to have this corrected properly.
