Mercedes Later Power Antenna Inspection, Removal and Repair - On Demand Video

Apples to models 1986 to 1995 with "TOOTHED" style antenna mast (read more in the description below

A non working power antenna can be very frustrating. Those original Hirschmann antennas are really quite reliable. They usually fail through neglect and lack of lubrication. But sometimes they just fail due to old age. If you understand how they work and know what to look for many times you can repair them yourself. Sometimes it will take a spare antenna for parts. Other times it may just need a good cleanup and lubrication. If you hear the antenna motor running and the mast is not going up or down it may just need a new mast installed.
