If you ever have to disconnect the small 12v battery located under the velour cover in the nearside of the boot, you will find the drivers' side window switches for the rear & passenger doors will no longer work & the scurity system is affected.
To rectify this after reconnecting 12v battery, go to each individual door switch on each individual door & fully lower & fully raise each window from their own door control, when you shut each door afterwards you will here 3 acknowledgement beeps.
That's it - all controls will now work fine & security system is back to its original state. :)
