My 2007 Seat Alhambra has issues with the central locking. When I lock either with the key fob or the drivers door switch only the drivers door and the fuel cover and the tailgate lock. There is no internal lights in the cabin working either in the front center or rear. Are all these internal lights and the central locking connected to the central locking control module? Where is the central locking control module located on the 2007 Seat Alhambra 2.0 CDI? As the three door are not locking I will open the cards and check the motors for current draw. I have checked all the fuses and found no fuses are blown. What is pointing me toward the central locking control module is the internal lights are not working in any position and unless I am mistaken are controlled by the central locking control module

Had the same , read the faults in central locking or convenience control,  mine was short to earth in both rear door locks, this is either wiring in the door looms or the rear door lock modules.  I  fixed mine by removing the  rear lock modules stripping them down and cleaning the commutators.
Not easy as its like opening a clock in there. Been perfect for 6 months since I done it.

Yes,  mine was exact same symptoms,  have you had fault codes read? I was convinced mine was central electronics unit fault , someone on here told me about cleaning the commutators,  there's not really any point in buying 2nd hand units as they are likely to be as old as yours.

Suggest you check the drivers door and tailgate wires at the same time, those are usually in a poor state as they get the most use, and just as likely to cause you problems in the other doors at the same time (or non working windows, alarm going off randomly, rear lights that don't work etc).

Update I stripped each of the door looms and checked each wire. I found that there was only one broken wire in the OSR door loom. on the plus side I found that the rear washer pipe had broken in the entrance to the rear tailgate. I still have the same issues in that the NSF and NSR and the OSR door are not locking and non of the internal lights are working. Has anyone got a wiring diagram for a 2007 SEAT Alhambra CDI or where can I find one?

Have a read of this thread, I think it matches your symptoms with the locking (ignore the clock and other bits though) https://www.fordmpv.com/smf2/ford-galaxy-vw-sharan-seat-alhambra/elec-advice-please-heatercentral-lockingclock-a'c/msg29103/#msg29103

I think I have the issues solved. The issues with the central locking was down to broken cables in the door looms in the drivers door, passenger door and the rear door on the drivers side. After removing and repairing the looms I still had the same issue that the when you locked the car with the remote only the drivers door , the diesel cap and the boot. I have since found that when I disconnected the drivers rear passenger door motor the rest of the doors all lock with no issues. I would suggest if you have all the door cards off and you have the same issue disconnect one door motor at a time to see if the rest of the doors close with the central locking. I have replaced the OSRD motor and the central locking is working perfectly again. The internal light issue was down to Fuse 53 blown which was more than likely caused by the broken wire in the door looms as the previous owner had replaced the 10A fuse with a 20A fuse and after repairing the door looms I have a 10A fuse back in and all the internal light are working with no issues. In conclusion the central locking issue  I had was down to the door looms broken cables and a faulty central locking motor. I also found that with the faulty central locking motor that the central locking was not operating every time now with the new motor it works every time first time. I want to thank brianh for all his help and input with the issues I had and for pointing me in the right direction to help me fix the issues I had with the central locking.

Good to know you have it sorted, Broken wires on the Galaxy/Sharan/Alhambara are a known problem point (the design isn't good - compare to other cars you start to see why they fail due to the angle involved in the door opening, most cars offset it to reduce the problem as well which they didn't do on these).

You may find that the old osr door motor can be fixed by cleaning the motor as described by Marcus above - a search for commutators should find the right post on here, least then you have a spare one for that door.
