Re: 166 central locking
front and back are different symptoms.
If the rear does not work, then chances are its that motor or wiring to it that is at fault.
the front, if say you open the drivers with the key and it the central locking locks it again, chances are its the passenger side at fault. This is because the motor and lock does not move, in effect of telling the system to lock again. Similarly when using the remote, watch the front pins, if one does up then back down again and the other does not move, it will be the one not moving at fault.
