W124 none moving rear headrests.

Hi,can anybody give me any ideas as to why the rear headrests are stuck in the up position on my E220ce.Also any pointers as to how they are actuated before I dive in to try and fix them.
While I'm here one of the headlamp wipers does'nt work either,any known faults I should be looking for.Thanks.
Paul.

Headlamp motors have a hard life, the only thing to do is to measure the voltage on the motor or use a bulb, you must try that first. If I can think of anyway to move the rear headrest I will come back, I have heard of this before.

Your rear headrest release is vacuum operated, here is the diagram;http://www.detali.ru/cat/oem_mb2.as...GM=717.413&CT=F&cat=15T&SID=80&SGR=150&SGN=07
If the rest of your vacuum system is operating ;central locking, headlight adjusters; I would look for a detached or damaged pipe .

Thanks for the advice chaps,as the rest of the vacuum system is working, I'm now hopefull that its just a damaged or dislodged pipe .As for the headlamp wiper I think I'll have to dive in and have a look.
Regards,

OK checked the pipework and there was a kinked supply pipe to the headrest
valve.Fixed that and still nothing but if I bypass the valve and connect the pipes directly the headrests drop.So how do I test this solenoid valve,I'm starting to think it might be a iffy dashboard switch,help!
Thanks,Paul.
