Hi i have  problem with sliding door we only use it manual with out power now it doesnt open any ideas thanks .

Mine passenger side door works sometimes not others, I've noticed this happens when the starter battery is low... I've yet to work out why the battery isn't charging fully all the time. 

Sorry if you have already checked, but has the inside lock been accidentally left on? I concur with comments about low state of 12v battery charge. It is important that the vehicle is driven regularly to maintain a decent level of charge. Failing that, use a trickle charger. I have successfully charged the battery using the emergency "jump start" terminal under the bonnet, as well as connecting charger leads directly to the battery while it remains in situ. I had my 10H model for 5 years And 26k miles, but have recently upgraded to a 30H model, which is equipped with a larger capacity 12v battery. I hope this may be of help and good luck with solving the problem.
