Silvia Club of NSW

Hi guys, just hoping someone has one of these lying around that they'd be happy to get a few bucks for. Am willing to collect or pay postage (I'm in Newcastle).
Basically, mine works, but is temperamental with the driver's side window winding down (fortunately, it always winds up). I have tested with the control unit from a friends' 180sx and it worked fine, so I'm confident this is the faulty part.

Here's 2 pictures, in case there's any confusion:

I would imagine the entire Silvia range would use the same part, but if someone wants to educate me, please do.

I did do a search and there may be some 'random parts' threads where someone has one available, but I didn't want to be irritating and bump a whole bunch of threads asking "have you got...?"

Thanks to dart_tarbo I had a closer look at the solder on my current control/relay - and have fixed it up good!

$260 for the part from the local Nissan dealership... glad I didn't have to go down that path!
