Finally someone with the same issue!! I have had exactly the same problem and its driving me crazy, as soon as i turn my key in the ignition my boot unlocks itself and it wont close unless i take my key out. Its almost like it locks it in an open position.
Ive tried changing the whole lock, checked the fuses including the ignition fuse and they are all fine, ive tried reseting my central locking system but nothing worked! However ive checked my wires and like you say they are damaged, so ill have a look into changing them.
Thanks for posting this !
Right i managed to change the wire for my boot lock, i got it off a 54 plate focus in a scrap yard, i connected the wires using crimps however the boot still opens when i turn the key in the ignition and wont close again as long as the ignition is still on. I dont know what else it could be !
Although when i open my boot i can hear the lock making an unusual noise, like its trying to lock its self, could it be the lock again ?
Please help its driving me insane ! Hate having a button in the front of my car that doesnt do anything now lol!
Did you patch the wires in the conduit or just inside the hatch itself?
If there is a break right up inside the rubber tube it can be hard to see.
If you repaired all the wires and it's still misbehaving then a replacement lock may well be in order.
This is how to replace it-
Im not to sure, i removed the black tape from around the 3 wires and i traced them as far back until the point i could see no damage because the wire closest to the lock had tears in the insulation and from there i connected the newer wire and still i had no luck.
However i think you may be right with the lock, when i first changed the lock i didnt realise how easy the key cylinder could be removed (as shown in your pdf), because i took the whole lock apart and basically went the long way around and i may have broken it in the process, ill get another lock and let you know my progress lol
Thanks again for the help!
We will get to the bottom of the problem even if it kills us ;)
Right finally!!! I have acutally managed to fix the problem after going throw 3 boot locks, replacing the wires twice and buying new fuses! All to find that the problem was in my hand, my cars fob was tripping the lock and whenever it was in the ignition it would open my boot.
I noticed at first that when i was driving my doors had a tendency to lock themselves so i took apart my key fob, cleaned it with some contact cleaner and that did it!! Everything works perfectly!
After all that!! Thought i would post this to help anyone else !
I wish i could say that this solved my problem but unfortunately it hasn't as my car does not have a key fob. i do believe it may just of been the cold affecting the electrics more as i also have the "doors locking themselves" problem but only in cold weather. Now its warmer i thought i would plug the wire back into the boot release motor and all works fine. *just like the doors arn't locking themselves atm*
