So the backstory first, as it is important to know in helping me figure out the problem. I locked my key in my 2003 X5 3.0L last summer and being hours from my home where the extra key was I had to call the local police to come out and help me get in the car. Well I now know that it is pretty much impossible to jimmy a lock on these cars and in the process of trying my wiring that goes into the drivers door lock actuator got completely mangled.

So I just didn't feel like dealing with the issue and was busy with work so for the last 6 months my remote and central door lock button only would lock/unlock the other 3 passenger doors and open the tailgate so I had to use the key to manually lock/unlock the drivers door when entering or exiting the vehicle. Keep in mind that during this time all windows and mirrors worked fine from all switches (Windows and mirrors come into play later in the story).

So a week ago I put the key in the drivers door to unlock it and the lock cylinder breaks. So now it's time to look into the issue and get everything fixed.

My dad owns a new car franchise dealership (non BMW) and he has one mechanic that's really good and he is the only one we let work on our cars when it's something that I can't DIY myself. So I ended up having to order an entire door from a well know junkyard because I needed several parts in the door that were destroyed while trying to get in the truck.

The door arrives and he spends a few hours replacing the mangled wiring harness, the door lock actuator, and manages to fix the lock cylinder with pieces from the door that we bought. So we get everything back together and still the drivers door will not unlock. All other doors unlock and all windows and mirrors are still operating fine. Another strange thing that ties into this is that the car thinks the drivers door is closed at all times. When I turn the truck off and open the door the interior lights don't come on and there is still power going to the drivers window even though the key is out of the ignition.

So we figure that the actuator must be bad and call the junkyard and they send out yet another door. We again instal the next door lock actuator and still nothing.

So that is one problem in itself that I need help with. But while I was troubleshooting I read somewhere that if I pull fuses 20 and 24 that it may help the drivers door lock work, so I do that and after reinstalling those fuses now I can only roll the drivers window up and down from the drivers door switch (auto up and down quit working though). I can also control the drivers mirror but not the passengers mirror from the switch. I can roll the windows up and down on the other doors from their single switches but the auto roll up and down also quit working on those as well.

So I'm at my wits end here guys and I need some suggestions of what I can do to fix these two different issues (that may very well be connected). If I can't figure this out its going to have to go to the dealer and I'm sure that will be easily thousands of dollars by the time they get done.

Thanks in advance for any suggestions. I've tried disconnecting the battery for over 20 minutes to let it reset. I've tried unplugging and plugging back in the drivers door window switch. I've also checked fuses 20,24, and 60 which are all part of the central locking system and they are good.

Please help I'm pulling what little hair I have left out from this. The truck is in fantastic cosmetic shape both inside and out and I have to have everything working right or it will drive me nuts. I'm just a perfectionist and I take pride in my beloved BMWs so this has to be right.
