I own a BMW E46 Touring on an 05 plate, i have a rear tailgate issue, the glass does not open with the micro switch positioned in the back, attached to the rear wiper housing! I have put a new micro switch on still no joy! I have been told that the Relay is faulty! Any idea which relay is the one i need to get checking on? I have five of them behind the glove box. One red in linethree green which are positioned on top of the box, and one which is sky blue in colour and postioned below the others on its own which is easy to get to, infact when i took it out, it killed the rear tailgate working with the switch, which works fine before, i put it back in and all works fine with the switch, but not the micro switch in the back!!
By the way this information about faulty relay has come from a mechanic with a diagnostic machine.
Any ideas please? It is driving me MAD!!!
