2002 C32 AMG
My driver side turn signal on the headlamp went out today, and upon removing the bulb socket I noticed one of the electrical contacts was severely corroded. Cleaning the corroded contact on the socket, and replacing the bulb did not fix the issue. I checked the service DVD, and there is a DTB out for this issue. Says to do the wiring harness upgrade. However, it gives no information on how to clean the contacts within the housing. I'm sure just cleaning the contacts would solve the problem short term... I see no way of getting access to the area with visibility unless you remove the entire headlamp assembly. Have any of you had any success cleaning the contacts without removing the assembly? Also, has anyone done a DIY repair job on the harness?
