HELP

I have searched the forum for answers as I am sure it will be covered some where but can't find anything
my 2003 2.7 will not unlock the drivers door by remote, all the others unlock, the key works, but it's not disarming the alarm, or the immobiliser, plus the windows will not wind down, also the left mirror will not move out although the right one will.
I have checked the body to door loom and found a break in the black wire, which is now repaired, checked all the others for continuity they seem OK but still no joy, any ideas would be much appreciated, even if it's only how much petrol I would need to burn it
