I'm new to the forums and this is my first post, so be nice.
I started experiencing issues with my central locking using the key fob or console button inside the car. The symptoms were slow locking/unlocking or not at all. The indicator lights would still flash and the interior lights would still come on. It got so bad the only way I could unlock the drivers door was by using the key and the passenger door had to stay locked.
I read various posts on the forums that pointed the issue to a faulty GM5 module and more specifically the relays inside. I followed some of the posts on here and decided to take the module out and send it away for repair. I got in contact with a really helpful guy called Paul Horner who replaced the relays for £35 (inc return delivery) and I can report I've re-fitted the module and all is working again. Paul is based in the UK and can be contacted on [email protected].
It was quite difficult to take the module out as I couldn't open my passenger door so I had to spend time upside down on the passenger seat, with my head under the glove box to remove the module. I would recommend taking the module out on the bracket as the nuts are easier to get to. You need to unscrew 2 screws holding the plastic cover underneath the glove box and then reach up inside and unplug 3 cables. All of them have plastic levers that have to be released before they can be unplugged. The 2 smaller connections need the bracket releasing in an upwards direction and the bigger connection requires the top of the plastic pushed to one side to release it. The bracket nuts can then be unscrewed and the bracket comes out.
Be aware once the module is out of the car, the interior lights, electric windows & roof, windscreen wipers and central locking do not work.
Hope this is helpful to someone.
