Dismantling a Land Rover window regulator switch LR013883 (from Discovery 3/4 & Freelander 2)

looks interesting, the rubber buttons are the same as used in desk phones. you can clean them with isopropyl alcohol, you can then use a lead pencil and just go over the black pad, this can return connectivity to the membrane button. Also as just 3 wires I wonder if this is CAN high Low and ground? there could be some value in the board if it has CAN transceivers, maybe just be a good place to tap into the CAN lines.

The circuit board has prob’ly got gunked up with polymer leaking from the rubber moulding, additionally you can buy the treated ( conductive) pads to repair each one or use kitchen foil in a pinch. Give it a try if it’s not in the bin 🙄

Thanks for the info. Even if I did fix it, its such a pain to fit in the car, I wont be trying to refit it. You have to take the door card off, which is ok. But then when I did this, one of the cables to the door lock broke - well the plastic end snapped off which holds it in the handle, so I ended up having to buy a new cable and take more of the door apart to fit this. Also removing this door switch pack from the top of the door card is harder than it should be and of course its snapped in with plastic lugs which break far too easily. It's one of those jobs which just always results in needing more parts!
