Hello everyone

So ive bought a 1994 323 GLXE as a daily car, only problem is that the central Locking isn't working quite right . The locking of the drivers door doesn't lock the other doors, but unlocking works fine . The Locking unit seems too have been replace with an aftermarket one from Fusion at some stage . You can hear the relay clicking on the opening off the door but not when closing . I will post up some pictures off the relay and aftermarket locking unit. Any input is greatly appreciated!

 

 

I had same problem... If the door locks are functioning properly at opening or closing, the relay seems to be faulty. The big red and blue are the open-close impulse output(+) for a second. One of them were very weak, was switching too short, so I have
changed the faulty relay. Now all is OK.
