Symptoms: None of your interior power locks work. Your door's keyholes do not activate power lock system. Your fuses are fine. Your remote keyless entry system still works and all of your doors respond to it.

The problem happens in older E36s with rust along the bottom, allowing water to get under the carpets. It causes 7 Red/Green wires inside a black plastic connector to rot out completely, leaving no electrical connection. To gain access to this plug, you'll need to pull up the carpet under the seats until you expose a hard white plastic coverish thing located underneath the carpet, just in front of the drivers seat.
At this point, I assume you are kneeling by the driver door opening, facing into the car. The white coverish thing will be towards the front of the car (your left) and the black plastic connector will be just right of the white cover thing, and towards you. The black plastic connector joins 7 Red/Green wires together and is attached to the chassis via a plastic, nutless bolt.
If you think that the wires are fine, give them a tug. You may be surprised to see that all 7 of the wires might fall out. My black connector was flooded with green copper oxide. I stripped all the wires down an inch, twisted them together, put a plug on them and then sealed the deal with tons of hockey tape and electrical tape.
Fixed my locks! :D

Hey everyone. I noticed that my central lock button, my driver+passenger door locks and my keyholes no longer trigger my central lock.
However, my central locking system (aftermarket, installed about 2 months ago) continues to work.
It seems to me my module is busted since I did tear open my trunk harness, patched up the jacketing of the wires, then replaced fuses 43 and 7. 35 must be fine since my remote power locks and my sunroof still work.
I'm thinking it's my module but it could be that one of my doors isn't registering as closed...but then I'm still doubtful my central lock remote would work. Regardless, does anyone have any ideas?
March 1st update
Fuel door NEVER locked with my aftermarket system. I did not wire it to (you're supposed to trigger lock+unlock at the same time), and as such, my fuel door only locked when I locked my trunk or driver door or something. This is not a problem.
My interior locks continue to be useless. The buttons, the driver door locks, the exterior keyholes do not trigger the central power locks as they should.
My battery also went dead overnight recently. I am not sure if that was becuase I may have left one of the aftermarket connections uncapped by accident (I fixed that) or because something in my car is draining current (which may explain why my power locks do not work).
My car currently draws 100mA or 0.1A when parked. Is this too much? I've disconnected the battery for the time being. I found out it's coming from Fuse 9, which I believe to be the radio. The radio was installed aftermarket by previous owner and is some flashy one...but it doesn't appear to be on. The PO did wire the car for subs, so maybe there's a short? I would assume that if there was a short...it would drain more than 100mA?
My next step is to pull the carpet below the drivers seat and see what's up.
Any further ideas, fellow e36 owners?
UPDATE
Latest update! I looked at the bentley manual and it shows that the central lock button and my door locks connect to the body control module at DIFFERENT PINS. The chances of both my wires going out at the exact same time is extremely slim. So I have concluded that I need to replace my GMIV module.
Hopefully this fixes everything!
