So today i decided to have a crack at th door module solder fix...
Got everything off quite quickly as my windows had dropped before....eventually managed to get the module out and when opened discovered that it wasn't in actually the "weak solder" problem at all but infact the little metal bits that go from the circuit to the main plug.
Off course i tried to solder this but........i melted the main plug (cause it was so close)...

Trying to put the thing together was a whole other struggle and after it was complete i still sat with a couple of bits

So now i'm sitting with not a faulty module but a completely f...... one!
Anybody have any ideas what now??
I suppose i'd need a new module?
Cost? part numbers?
