The central locking on my ZX has recently packed up (totally!). As first I suspected the wires from the door to the dash, but my local garage has checked these and said they're fine (one of the electric windows wouldn't work from the driver's side, leading me to suspect the wiring, but this has been traced to a dodgy switch).
The CL has never worked well from the plip since I've had it (the driver's door motor didn't seem to be able to lock it) but has always worked from the key. Suddenly it's dead, with no response either from the key or the plip.
Reading the info on this forum, I suspect the CL control unit has packed up. I've checked it's 12V feed, which is OK. All the contacts on the connector block are fine. The alarm still sets OK with the plip (with or without the CL box connected).
Am I likely to be on the right track? And if so, has anybody got a spare CL control unit to sell?
Thanks,
James

Dead sure the CL unit is dead ?
If its loated in the center box, there is high possibility that an earth has failed. Lift up the carpetting - and look for bolts with lots of wires bolted into the body sheeting. Some of the wires may even have snapped off by the copper rotten away completely.
Thats what I've seen on BX'es anyway.

Thanks for the quick reply Anders.
It's behind the dash on my car (next to the fuse box). Although I must admit I never checked the earth connection!
The wiring diagrams show the earth going to a common earthing point, so I doubt that is the cause. All the wiring looks to be in good condition actually.

Update
'New' control unit arrived today. Central locking is now returned to it's previous state (i.e. works with the key only), which is good enough for me to be honest. When using the plip, the driver's door doesn't lock or unlock. Must get around to changing the motor for the one I bought from Stewart (oily) quite some time ago...
