'98 E300TD Driver's-side Side Rear View Mirror

[Toni]

The mirror can be folded back alongside the car body, as it is springloaded back into position. When I folded it back today, there was a sickening "snap" and the spring came loose inside. I removed to mirror ASSY from the car by removing the 3 holding screws and disconnecting the 2 electrical connectors (I wanted to remove the exterior glass, in an attempt to extirpate the so-called self-dimming feature which had miserably failed; and now I do have what appears to be a clear usable mirror) but now I don't know how to reconnect the spring within the "guts of the mirror ASSY... I can see where the spring attaches to the fixed-to-the-car (via the screws) part of the Assy, but not where it attaches inside the tunnel... I will be thankful for any help...
