electricians help!
 

right so my window wont wind up and im pretty sure its the relay in the bcu which means changing that, the ecu and key fobs, lots of money needed. Howver i think you could probably use the power from the electric mirrors wire that into the switch and get a working window again. Does anyone know where i can get the diagrams for the wiring in the door? or any advice? Thanks guys

A new relay would be cheapest I think.
