I was able to fix my power antenna. When I bench tested my antenna, the motor was working but the mast was not moving. I pulled the mast and put it back and still did not work. I opened it and found out that the gear inside was no longer engaging. I found an aftermarket gear made by AntennaMastRus and installed it and now my antenna works.


I also replaced the seals:

• Mast Lower Seal - Mercedes-Benz (201-827-05-98-64-7C45) - https://mbparts.mbusa.com/oem-parts/...bC1sNC1nYXM%3D
• Mast Upper Seal - Mercedes-Benz (201-827-04-98-64-7C45) - https://mbparts.mbusa.com/oem-parts/...bC1sNC1nYXM%3D

Hope someone finds this useful. Just sharing.
