Q: Turn signal issue

asked by on October 17, 2016

Driver's Side Turn Signal is not working properly when headlights are on - blinking as if a bulb is out, but bulbs are fine. No issues at all when headlights are off (daytime). Friends have suggested a ground issue, but I do not know where to start to look in order to fix the issue myself.

Thanks in advance for any help you can offer.

My car has 155000 miles.
My car has an automatic transmission.
