I have switched out the bulb, but the light does not work?

 

Check your ground(s)

Use a meter to see if power is getting to the harness.

 

Fuse blown...?

 

My 09 had a crappy connection right at the connector, kept changing bulbs thinking it was blowing them all the time. Finally figured out it was the connector and made up my own disconnect to the headlight. No problems since.

 

Just talked with a guy last night who has a 2009 Laramie. Said his front driver headlight quit working and when he took it in to the dealership, they did something with his vehicle computer and it fixed it.
