Title: door wires boot
Post by: marinabrid on July 11, 2014, 07:23:08 PM
Looks like i have the broken wire syndrome,   never had it in 12 years with the Mk1  but the central lock and window don't work on rear pass door.  Have looked at the link  how to do the job  but maybe I'm not reading it right,  do you..
unscrew the lock ring   then remove it to then pull the boot from the inside of the door   over the plug  but not all the way so as to remove it   or looking at the same thread on Galaxy.org    on there it seems to say push the boot inwards towards the door   away from the plug. which is the right way to access the wires,  also it says  if there are a few wires  remove the door card and unplug from inside.    where the wires go into the door itself   is there a lug that you can't see to simply   unplug ?

Unscrew the  ring, when the plug is unplugged carefully pull the plug and the gaiter the gaiter only sits in a groove in the door, once the gaiter is clear of the door and kept close to the plug you should be able to see the wires clearly.
The problem is the gaiter will get in the way of any repairs you do so you need to decide whether you can work with it there or to partly remove it, I say partly because it's a bugger to get over the plug.
The other option is to unplug all the connections inside  the door and pull the loom out far enough to work on .
all really depends on how bad it is.

ok  got that   thats where the spray silicone seems to come in,  the gaiter is pulled part way towards and partly over the plug to expose the wires.  will see how it goes another day.

hi all,   thought i would repair rear pass door wires,  what a sod of a job,  the boot sure don't want to come over the plug  its so tight !  anyway taped up some wires  repaired a couple of others and all is back working as it should. 
thought i would look at front door,   i released the nut  but as i was turing it was also turning the thing in the door piller   is there a knack of holding this one still  as otherwise I'm just going round and round  no doubt twisting the wires     i nipped it back up and as everything is working   thought id leave well alone.

Remove the scuff/trim panel, you can the keep pressure on the rear of the socket, unfortunately the locking ring that holds the socket in place doesn't do a very good job.

found these on ebay    looks to me like they may work on the door looms for non experts at soldering joints

not sure if that link works    heres the item simple to find on ebay
a connector you put the wire in each end   heat it with gun and it solders and heat shrinks in one job    anyone used them ?

I've used them at work.  They will unfortunately leave a stiff section in the cable that is quite (relatively speaking) long. As the wires need to be flexible with the repeated bending, I suspect they will fail again sooner.
The remaining insulation is probably already degraded (with time and the extra heat caused by the failing strands increasing resistance).

Unfortunately the best thing to do is to replace the existing wire with new.

Not had to do this yet, but expect it to be soon as my drivers door speaker is quiet and the one-touch window operation keeps needing resetting.

maybe some expert  could show the best way to splice a new piece in  as i tried and made a pigs ear    but did the best for an amateur.

thats the one i followed   but to a soldering novice    it don't show how to solder two wires and splice it together, thats if there a right way and a wrong way to do it, especially the thicker wires.

Your right it isn't particularly easy.  The bigger ones get harder to do because they need more heat and the thicker copper pulls away the heat faster too. Then once joined the solder takes a bit longer to cool enough to hold the wires too.

Unfortunately it's a matter of practice.
