PLEASE help...... I am experiencing a problem with the central locking. I will describe as fully as possible.
The Vehicle is a 2004 LR Discovery II TD5 Facelift model.
A short time ago, we had a little crash. It didn't render the vehicle un-drivable but did require an insurance claim to deal with the damage to the front of the vehicle. When the vehicle was repaired and returned to us, all seemed fine but soon after we noticed a problem with the locking. As foillows:
1. Locking fron the fob works perfectly
2. Locking at 5mph works perfectly
3. Locking from the dash switch works perfectly
4. Locking from the key works perfectly.
5. Unlocking from the fob, key or switch does not unlock the two rear doors
6. Unlocking from the fob, key or swith works for the two front doors and the tail-gate.

I have checked and re-checked the obvious issues and have concluded that I know nothing about car electrics. Using logic instead of ability in these matters, my opinions are as follows:
1. Cannot be an actuator as both doors malfunctioned at the same time;
2. Cannot be the tiny springs as both doors malfunctioned at the same time;
3. Cannot be a broken wire as both doors malfunctioned at the same time;
4. I have checked the child-locks but it can't be this as it is able to open from the inside using the handle !
I have changed the battery in the fob and have put WD40 in the door latch ???
PLEASE HELP. Unfortunately we have no easy way of getting to a LR Main Dealer as there isn't one within a three hour drive !!!!
I have brought it to a local mechanic who has plugged it into a diagnostic unit and no errors on the central locking are showing up.
Has anyone got any idea what I can do to fix the problem.
Thanks in advance
