Fixing Power Window Amplifier?

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! :)

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

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

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!

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      Ethanol Content Sensor - Always at 11%?

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
