Rear Door Not Locking

[davewill]

I've got a 2006 Mkll model, and the problem is that the rear offside door doesn't always lock, and then again if it does lock, doesn't always open when the remote fob is pressed

 

It started last week when we had a lot of frost and freezing weather

 

Its still under warranty so i'm taking it in soon for frauds to have a look at it

 

I was just wondering though, is there a motor on each door that activates and then de-activates the locking mechanism?

 

If not any thoughts as to why this lock and unlock problem should occur?

 

Thanks

There is a solenoid in each door, but the problem is highly likely to be the wires in the loom between the door and the b pillar (inside the rubber boot). They often break, not just the conductor usually the insulation is broken too so if you pull back the boot the problem should be self evident.

 

The galaxy door looms are rubbish and this is probably the best place to look.
