My turn signal lights on the driver side. Want work change the relay and the light

Check for corrosion in the bulb socket. Also try using bulb grease on the bulbs.. Check each socket for power and ground. If one is missing that's will give us a better idea as to what's going on with them. Does one bulb come on solid and the other nothing at all? If so check the one that's doing nothing at all.

I had the same problem....the whole left side turn signals did not work so I changed my turn signal control module...it's on YouTube...

On my 2002 park av. my rt. blinker suddenly would just stay on solid, I switched out the front cornering lamp (the one next to the h.lamp) with a l.e.d. type. apparently, there was too much of a draw on the system?? maybe the flasher module? anyhow easier and cheaper fix.
