W202 central locking problem

[markymark1]

Hi just about to start using the merc again after couple of months, i disconnected the battery when it was left.
Got in today opened the the boot manually connected the battery and it started first turn took for a drive to get washed but the central locking does not work.
The alarm works as i can arm it and after a while if the door is opened the alarm lights flash (disconected the sounder)and it can be disarmed (red led to arm green to disarm) i think that a 15a controls the central locking but the other things on this fuse work ie interior/boot light, are there any more fuses for the central locking? Am i right to beleive that the rear headrests are also connected to the central locking pump as these work fine but no central locking from either the key or the switch on the centre console.
Regards Mark

the rear headrest come off a vaccum on the inlet manifold!
not from the central locking pump!
