My 2005 S500 remote door locking system just works in the IR mode (and poorly at that) with no RF function. The batteries in both key fobs are new and the radio reception in AM and FM is fine.
Based on my searches and reading here, the issue is likely the amplifier that gets its signal from the rear antenna. The antenna would seem fine since I have no radio reception issues. It may just be a loose connection but the consensus seems to point to the amp.
As I understand it this amp in under the headliner at the top of the rear glass. Has anyone attempted this repair or have removed the headliner for any other reason? It seems like a pain to remove so I’m looking for pointers from anyone that has done it.
Thanks,
John
