    trying so find the fault
    A) Rear headrests wont go down and B) Lumbar support wont pump up or down.

    The issue is which fuses are relevant.

    OK Fuse 40 7.5 Amps runs the Rear Head Rest release, apparently the Hazerds are on the same fuse and they work fine ... so rules out.

    Allegedly the Lumbar support and the powered lift and release on the rear head rests are all run from the same PSE.

    So I am trying to find which fuse supports this pump.
    Sadly no PSE pump on the original fuse list

    There are fuses for
    1.Dynamic Seats. [ I suspect this is the massaging bit. Added to Multicontour seats??? ]
    2.Multicontour Seats. I dont have these but would the basic Lumbar bag air pump use the same fuses?

    My seats are basic ones with Lumbar Supports ( one in back of seat ) and Cooled and heated Climatic Ventilation. code 401.

    On the fuse list the only other relevant thing I can see is
    CA Headrests ..... what is that?

    Any ideas welcomed.

    Probably not the same, but on my wife's Slk some things stopped working because the PSE was sitting in water and the circuit board was rotted away. Malcolm (Television, sadly missed) kindly rewired it for me so it sat the other way up in the car and sent it back to me. Just a thought.
