Driver Side Brake Lights Not Working
 

I have a 2002 300m and the driver's side brake lights are not working. Power is coming from the brake switch fine, and the center and passenger side brake lights also are working fine. The bulbs are good, but the hot wire coming from the switch must split at some point, and I'm not sure where that would be. Anyone else had this problem, or at least know where I can find the point where the hot wire splits into left, center, and right feeds? Thanks a lot.

Wires to the rear come thru the body at the left (drivers side) corner of the trunk, just at the base of the wheel well. That is the last connector untill you get to the lamp assemblies. Harness exits the trunk then follows behind the bumper cover to the tail lights. Have seen ground pin of the connector at the light corroded a few times....

Thanks for the response. The pins all seem clean, is there a way to test the ground at the lamp?

Just a thought, are your running lights working properly? When my running light bulbs go out, my brake lights stop working...you might want to check just in case.
