QUOTE(Tech @ Feb 14 2005, 08:47 PM)There is a relay under the dash on the drivers side towards the left side.Most of the time the are marked on the relay.It should say central lock or something like that.
Hi, Tech. I also have a problem with the central-locking. But the problem is the tailgate locking. If I lock the tailgate, the central-locking in the car would go hay-wire. For instance, I have to manually push down the lock on the passenger car first from insidethe car, before I can centrally-lock with the driver's side lock on the outside. If not, only the driver's side would go locked. The same is true for the passenger side lock.
However, if I leave the tailgate unlocked, I can lock the car from anyone of the two driver or passenger doors. No problem one.
The tailgate lock might be bad causing the system to short.You will need to remove the rear door panel and unplug the lock and see if the system works normal.If it does then the rear lock is bad.If it doesn't then it might be wiring.
