So I had the opportunity to delve into this problem again on my brother’s 1989 300TE- rear left window going down spontaneously. As many of you suspected the problem does indeed lie in the wiring harness between the b pillar and rear door. One wire is sheared in half while others have cracked and missing insulation. How do I fix this? Is there a replacement window harness available? I can’t see crimping the wires together working in this location as the flexing from door opening and closing will cause the repair to fail in short order.
