Central locking fault

[e30-unit-soldier]

Car will unlock from all locks drivers door passenger door and boot however it won't lock from any...

I followed the wiki guide and connected the red/black wires and that hasn't rectified the fault it's still the exact same.

Any ideas as to what to do next?...

Anyone???

I've taken out the relay and the thermal breaker is still intact. I tried to ground the lock and unlock wires and got no response...

Still all the same car unlocks every lock but won't lock.

Check the boot set up is all connected and moving. Sounds like a problem a friend had on his. Turned out to be the link arm had come off
