    Thanks. This sounds promising. however, I had my door handle off yesterday and could see no wires, are the micro switches on the actual latch where it locks to the chassis?

    Interesting, @Saint.V8 I get the Adobe 4 splash screen but it then just dies and no further screens appear. Only happened since the most recent Win10 Pro update last week. I shall investigate further. Good to know it works for some users.
    I've run it in Admin mode too and that makes no difference.

    The micro switches are internal to the lock assembly.

    The windows are likely to be the switch pack, can you close the windows with the lazy locking feature? Lock with the FOB and keep the lock button pressed for 10 seconds.

    My copy of RAVE goes through 3 Adobe error screens to start on XP but works without the error screens on Win 10 64 bit home edition.

    Hi @Datatek - Good to hear from you.

    I wish I could test, the key fob has not worked since I bought the car two years ago - so one of my next/current tasks is to see if I can get that working. However, I will try holding the key in the lock position as I think that should also activate the lazy lock feature and let you know.

    I'll see if I can do a screenshot video of it working and see if you can spot any issues on your box!

    I have had a bit of a "dabble" and the reader in the CD's fires up but declares the files are unreadable (encrypted) so exits.
    Tried to open the files with Acrobat Reader (just installed this morning) and it says the files cannot be read.
    So does Nitro-Reader.
    I am wondering what has managed to encrypt the files without me knowing it?
    The files are there visible in the *.iso "wrapper" that I mount under windows 10.
    It is very odd indeed.

    I tried the key in the lock method of triggering lazy locking, which did not work at all - so for example, I wound down the drivers side window too so that if lazy locking kicked in I would see the drivers side go up regardless of whether or not the passenger side did - but neither did. However, I can put the drivers side up on the switch pack.

    I don't think it is the switch pack because I can hear a faint click from the passenger window when attempting to wind it up.

    It feels as if the tailgate and passenger window are related due to when they occurred.

    Some photo's of the door lock assembly & microswitches. On the couple I have taken apart, it's the little black plastic pip on the switch that has broken off, so the snap action either operates but is on the threshold which causes phantom locking or the switch does not operate.

    Thanks @Datatek I will examine this in detail at leisure. Really helpful.Thanks. More to follow on this. I'm coming round to multiple co-incidental faults - earth problems on the tailgate via drives door, various compounded problems on the door locks, perhaps issues with the switch pack too.

    I would say you definitely have a switchpack problem if the rear/left isn't working from it at all. Front/Left... erm, could be switch pack related, but could also be the outstation in the door where the relay is. It's a double coil/contact relay, so by default the output pins to the motor are both grounded - then when you go 'Up' or 'Down' it energises one of the coils to put 12V on one of the wires to make the motor move in each direction.

    One thing you could try... pop the door cards off the front doors (you'll need to take the drivers one off to check the latch microswitches anyway). If you swap the door outstations between the doors, does the passenger window then go up? If so, then the relay in the outstation or the driver circuit for the 'up' portion has failed. If it still doesn't go up, and the drivers window still works as normal, then it's the switchpack aswell.

    I have a refurbished switchpack without sunroof available on exchange on my website if you do need one.

    Tailgate - it does lock/unlock through the drivers door latch, but if that tests OK, then the actual switch in the tailgate is known for corroding aswell.
    Hope this helps,
    Marty

    You were spot on as usual. Replaced the Switch pack and that fixed the windows problem. The tailgate issue was a broken button. Thanks for your help.

    Marty, Thanks you were right too.

    I missed your offer and bought a replacement switch pack - where is your site, I could have bought yours.
    Also - I have the old one - if you re-furbish them you can have it.

    Glad you got it sorted. I use an alternative switch button for the boot, less expensive and likely to be more reliable

    No problem - I try not to blatently paste my website everywhere, as I'm more into the forums to try and help people, rather than make a quick buck! But ask and you shall receive... p38webshop.co.uk is my website for most of my P38 related parts that I work on. If you don't want the old one, then I'll be happy to take it off your hands (obviously happy to pay postage etc!) - I've got a load of switchpacks on my bench that I've just stripped down to start repairing, and found another couple aswell... looks like I know what I'm going to be doing for the next couple of days!!

    Glad you got it sorted though and it was an easy fix!

    Hi Marty, Thanks - looks good. I'll be up your way on Sunday, driving the Ridgeway. If you are out and about I could bring it with me and give it you! Otherwise I'll be happy to wrap it up and post it.
