I have managed to fix 1 problem with my central locking.
There were vaccum leaks in the pse which have now been fixed.
I reconnected the pse and the central locking works but there are still problems

1. Interior boot light switch stays on for a while then goes out
2. Curtesy lights stay on all the time (overhead and in the doors) have to manually switch them off before leaving car.
3. When operating indicators they flash really quickly.
4. Rear head restraint button works but locks the doors as well
5. dashboard door lock switch opens doors but doesnt lock them
6. Alarm does not activate

Any ideas or help would be appreciated

Thanks
