e39 Drivers Side Door
I'm having some issues and I think I may have tracked down the issue but I was wondering if I could get some pointers on how to verify/fix. First let me say the car is a 1996 e39 523i.
Yesterday morning all was well, drove to work, rolled down my window, etc. I arrived at work, rolled my window back up, got out and used the remote to lock the car up. I went back out to my car around 2 in the afternoon and hit the button to unlock the doors and all the doors unlocked except the drivers side.
So I climbed over from the passenger side and tried to open it from the inside (thinking maybe the actuator died), the lock would raise, then drop as soon as I released the handle. I tried holding the lock up while trying to open from the outside (reaching in through the back window) and I couldn't get it open. After way too much searching I was worried I was going to have to tear up the interior to get the door open when I saw someone mention trying the key (manually) but turning it almost 90 degrees. I tried it and thought my key was going to break but it worked (I guess no one has done that in the past 18 years and it was just stuck).
After I got home I checked all the fuses (under the hood, in the glovebox, and in the trunk) all of them were good. I was about to try to take the switch out (sadly most of my tools are in America and I'm in the UK) and I noticed that the buttons on the switch light up when the lights are on just like they are supposed to.
Does anyone have the wiring diagram for the switch so I can verify it is getting power (to make sure a wire isn't broken)? I really appreciate anyone that was able to stick with me through this long post and any assistance it extremely appreciated!
