Fixing Power Window Amplifier?

[slimjim]

My drivers side power window has stopped working recently. Before it stopped completely, I could hit the door with my elbow and it would come down, but now it won't budge at all.

I'm pretty sure its not the actual window winding motor as before it died, it never slowed down or anything, it seems as though it's not getting the electrical signal to 'go down'.

So when I use the button, I can hear a clicking coming from the power window amplifier (I think its called), this little black box -

So I pulled it open

And here are the two switches that connect when I pull up or down on the button for the window.

The one on the left is up and the one on the right is down.

So they're both working, but I think perhaps the connection might be dirty or something? What can I use to clean up the connection, its too small for me to even see if its got anything on there.

Has anyone attempted to fix this before? Does it sound like this could be the source of my problem? Its pretty damn annoying not being able to put down my window. No drive through Maccas!

There was another post here somewhere in the last couple of days, tell you how to fix this.

Here it is

Cheers mate, I searched just over a week ago for an answer, naughty me for not searching again before making this topic!

I can't seem to locate any dry solder joints though, am I sposed to be looking on the top or bottom of the circuit board? Is the ring you described in the other thread a burn or something? I got no idea about circuit boards...?

Thanks

its underneath where the relay coils are, on the circuit board itself. The "rings" are simply where the solder is not contacting the wire that comes through the circuit board.

Ahh ok. As far as I can see, everything is soldered up nicely...

...which means the problem must lie elsewhere. DAMMIT why couldn't it be something easily fixable!

Actually on closer inspection, I think one of the solder points is stuffed, one that connects to the bit that the plug plugs into... must be the outgoing signal. Maybe thats why the switches still work, but the window doesn't... signal goes in, but doesn't come out?

Either way, I'm gonna take it down to a TV repairer tomorrow and get that point soldered up since I don't have a soldering iron... will let you know!
