Locked, Door Locks

[Bear]

1990 325ic (kids car, they are in Korea for two years and I am car sitting)and the drivers door lock will not lock with the key. I can lock it using the interior door lock/unlock knob and I can unlock it from outside with a key. Passenger side is locked tight and will not unlock with key or interior knob. Trunk will lock and unlock with the key. I replaced fuse #27 but that did not help, I have a Haynes but not a Bentley so I have no way to determine where the relay (if any resides for central locking). I have a ETK andETM but the ETM is new and does not include the E30 wiring diagrams. I suspect and electrcal glitch within the central locking system and any help greatly appreciated. I am at lazybears2@cox.net.

PS: I thought my 1988 750 was tough to diagnose, silly me.

The central/locking relay/control unit is mount above the right front foot well speaker inside the “A” pillar if you take the speaker cover off and then remove the speaker above the speaker hole you’ll see two cross-point screw heads undo these and the central/locking control unit will come down. If you take the top off the unit inside there’s a three-legged solder fuse you can solder this back together. The other common fault this E 30 c/locking is the main power supply to the ECU this runes in and out of the door and the pins in the “A” pillar block connector corrode and stop power getting to the ECU
