Central Locking Failure

[2rismo]

Over the past few weeks, my central locking has been fading.

The motors still work properly, the immobiliser activates and deactivates correctly, the hazards flash how they're supposed to when i push the button on the remote.

What DOESN'T happen is the doors unlocking from the remote. I can unlock both doors with the key, the drivers side does both and the passenger just does that side. The switch for the passenger door on the drivers arm rest works and both sides operate correctly when you're in the car.

It's as if the signal is getting to the immobiliser but not the locks.

Does anyone have any suggestions? The problem was happening intermittently and is now an 'all the time' affair.

Thanks in Advance,

Adrian

The alarm solenoid 'piggybacks' the normal central locking. Its simply held in place by a screw that locks onto the existing arm. Sometimes the screw works loose.

Pull the trim off the driver's door and reset the alarm solenoid.

In addition to the mechanical linkage, also check the driver side doorlock actuator itself. The actuator has an electric motor in it which may have blown, or the gears maybe stuffed.
