Greetings to the group. My W203 C270cdi blows the 30A fuse for the drivers' seat immediately when I attempt to adjust it while sitting in it. If I get out of the car and take the weight (190 lbs) off the seat, it works fine. The passenger seat works fine all the time. I've taken the seat out and looked at the wiring loom/harness underneath, it seems fine, no visible dead short or anything like that. What should I try next?
