Hi, hoping someone can point me in the right direction.

I have a 94 JDM GT Legacy wagon (BG5) which has an intermittent central locking fault. When opening the driver's door (right side), the central locking sometimes works, sometimes not. If not working, I can "reset" it by disconnecting the battery and reconnecting. So is obviously not the switch in the door or loose wiring etc, seems likely is the component that controls central locking.

My question is: where is this component on this model? Is this the likely culprit? Anyone else had a similar experience or have any words of wisdom?

Looking at various wiring diagrams on the internet for other 2nd gen models, it looks like the "door lock timer" is up behind the glove box on the left hand passenger side. I don't want to start pulling things to bits just yet though if someone can point me in the right direction.

Thanks
