    Yes your right Brain went into meltdown after seeing those drawings.... anyway I did the test for power as you said I'm getting +12v then -12v when i turn lock (well when daughter turns lock) so there is power going to the actuators, so looks like another trip to the knackers yard for me then, see if i can get two motors

    So did you garage the car with the locks working and when you put it back on the road they didn't work, or was it after using it for a while. Just wondering if anything is siezed, but you're probably on the right track.

    No the locks aren't seized, took one of the actuators out and you can turn the cog until it clicks so they seem free enough, what I did try on the bench was to wire up a 12v supply, just a couple of wires negative onto where the blue/grey would connect to, and touched where white and black would be in turn, but nothing happened should it have moved with touching with the live to white or black, how ever I did get a sort of a noise of the small motor when i put a 3.5v charge through it but this wasn't enough to make it move fully. sorry if you can't understand what I did but difficult to explain in writing

    not sure what position the thing would be in when dismantled. You would either test it like you said or opposite polarity with the + on the blue/grey

    Here is a pic of actuator for a e34 attached to the locking mechanism but is the same one for a E36. You can see the three pins for connecting the cable plug on the blue coloured connector.
    The top pin is for the blue/grey then black then white at the bottom. the other thing that i noticed in this picture, was how well it is attached to the lock, mines wasn't actually, it was very loose.
    I didn't take the lock out, I removed the actuator by putting my hand up into the door and it really just fell out so thinking it might not have been attached very well to the lock it might have just worked its self loose over the years.

    I'm going to give it a few more tests before I go to the scrap yard. I'll let you know what I find and if I get it fixed.

    Well I done ever test to get it to work but to no avail.
    Of to the knackers yard got two actuators out off a dead E36 10 quid, fitted them to mine and yes there all working fine now no problems .
    so after all that, replacement actuators done the trick,
    but you've got to test before you throw money away don't you agree could have been the module.

    It's probably usually the actuators, but I like to check that it's nothing else before buying something I don't need. Its just diagnosis and narrowing it down till you're sure. Either way, it's good you got it sorted and it's all good learning for all involved. You know how they work now.
