Central Locking

[scrappydoo]

Wonder if anyone can help...

 

I have seen similar problems to mine posted on this great site, but have tried most if not all of the fixes that have worked for everyone else, but without success:

 

It started off intermittently but became permanent after a couple of weeks (this is a Mk1 W reg 2000 Galaxy):

 

If I unlock/lock with the boot lock all doors unlock except the driver's; both front windows roll down/up as usual if the key is held in position long enough, but I always have to unlock/lock the drivers door separately and always in the sequence boot first then driver door, otherwise during the locking sequence if I lock the driver door first then boot, the driver's door unlocks! Along with this, occasionally the fuel filler cap will not unlock but I have seen no pattern as to when it will or won't unlock.

 

I have inspected the wiring loom in the drivers door gaiter and as far as i can see inside the door, but see no evidence of chafed wires and no related fuses appear to have blown

 

Any help/suggestions would be much appreciated

do the windows work with the switches - the global closing (key in lock) use different wires i think - still may be wiring problem check tailgate wiring and other doors - for shorts and broken insulation

 

btw the wires break inside the insulation so its not just chafing you are looking for - have another look at the drivers door

Thanks for the reply

- the windows work with the switches as normal, the global closing works from the boot lock, but not the driver's door lock (passenger lock knackered since I've had it)

 

I did look at the tailgate gaiter wiring - when I looked in there it looked like a small bomb had gone off! - a black and blue thickish wire (2.5mm crimp worked) had broken, brown/red, yellow/black, and red/yellow wires all had broken insulation and bare wires exposed, in addition to which both hi-level brake light wires had broken

 

All crimped/insulation taped as required, but perhaps I should have a look and see if I missed any others: (I knew the hi-level brake lights weren't working and pleased that I've fixed them now but don't know if I've inadvertently fixed anything else!)

 

I will look again at the driver door wiring and other doors, but any idea of the coloured wires I should focus on for the locking and is there an easy way of detecting broken wires within an unbroken insulation? Avometer, I suppose?

Problem sorted now: a good mate came round, had a look at a wiring diagram and traced back to a splice where all 6 wires (5 doors + fuel filler door) + feed are spliced together - guess the location: front passenger footwell where the rear wash/wipe pipe has a well known joint which frequently splits and which I have been a victim of...

 

The point where the splice is, was absolutely soaked and the wires were all corroded (pictures to follow when I'm allowed to post them).

Wires re-spliced and heat shrunk and the central locking now works fine!

Cost: a curry and a couple of beers :rolleyes:

Glad you got it sorted, you should be able to post pics if not now then with your next post. :rolleyes:
