I think this post rather answers what you have asked....Hi Nodge,
Tried Soldering the wires to the Brown things attached to window but soldering Iron old and not good enough and the 2 Brown things fell off. awahat do I do now. PLEASE.
They should be attached to the glass as above. Probs easier to get new glass and plug them on. Might have blown fuse if in door loose. No need to take door handle off !!!
