left front turn signal is dim. Also, when I put the hazards on, the left turn signal is dim? I just replaced the turn signal bulb in front. I plan to go back and check the socket which I did not do that. Maybe contact is bad. But if it is a grounding problem how do I fix that?
If it’s a grounding problem you have to clean and re-tighten the ground connection.
Cleaning the contacts in the socket may also help.
