SL55 central locking

[mark.rowe]

I have been working away for 3 weeks and when I returned home my central locking is no longer working. Took it to the dealers and they replaced the fuse but it blew straight away, didn't have time to look at it properly as I had to leave for Germany again, this time taking the car with me.
Has anyone had similar problems, or any ideas what the fault could be?
Seat massagers have also stopped working.

Cheers
Mark.

Usually a sign of water ingress in the boot on SL's, the Keyless Go control unit often takes the brunt of it which could obviously interfere with the central locking, it's worth having a look for signs of moisture.

agree with that, any electrical problems and the forst port of call is the boot, have a good feel about and see what you can find....

just having the rear window seal on my replaced by merc for the same reason, albeit its litrally a tiny tiny leak at the mo

Cheers for the replies.
I'll take a look around in the boot, I don't have keeless go but maybe something else has got damp or damaged, someone else mentioned the central locking pump which is also in the boot.
Are the two seat massagers somehow linked to this pump? Both seats massage and lumbar support have also stopped working and all where working fine until now.

yeah your seats will share the same pneumatic supply as the central locking (PSE), sounds like there's a problem there.
