Hey guys, this is my first post but I read around here alot and though I might help out. I saw a few threads about people having trouble with their windows, and half the time it ends up being the amp, like mine...

I read someone posted sometimes a connection within the amp box can go bad so I thought I'd provide pictures! with some info!

Items needed:1.Solder2.Soldering Iron3.Philipshead screwdriver(for takin off ur door!)4.and a small flat head screwdriver for taking apart the amp box.

If you don't know already the window amp is located in the drivers side door, and for an s14 its a small white box that looks like this

after removing it, you gotta pry the black face with the 8 prongs off. there are snaps at these locations on the box. I kinda chipped of a bit of it cause I was rushing a bit.

After you open it up, CAREFULLY pull out the circuit board...

Flip it over and take a close look... you can see a broken connection that is easily fixable...

Heat up your soldering iron, and solder the broken connection, something like this...

let the solder cool for a few seconds, and slide the board back in! you might have some trouble if its the same connection as mine, since the sides of the box hold the board in. I had to resolder thinner to let it slide in. put it back together and roll down your window and enjoy the breeze! If you discover it is a bad connection, and follow these steps to fix it, you save yourself ~$160 from the dealer or ~$60 from ordering it online!

I hope this helps...!

i know this is an old thread but The problem is i think it may be the window amplifier, the window wont go up or down, the window was going up and it just stop going up almost half way. When i keep pressing the button for it to go up it just clicks. Guy i bought the car from says its the window amplifier so thats why i am saying it possibly is. If anyone is in the Raleigh or Garner area it would be nice to get some help even if i could just use someones to just get the window up that would be great. This car is still new to me some i'm learing new things everyday. If anyone is located in Raleigh or Ganer N.C. i would really appreciate some help.

Also when i pulled mines out there isnt a burnt part like u have in the rectangle. There isnt even anything silver in that sport. Any other ideals?

replace it and check your window tracks for obstruction, then clean and lubricate them.

check all your wiring as well.

Yeah, this was the best repair I ever did. Saved myself sooooo much money. I thought someone already did a write-up on this? Either way, nice job!

just try and have someone press the button to roll the window up and manually pull the window up at the same time. This has worked many times when my pass side window was not working, then one day it started working again..don't know what happened.

hmmmmm, you're gonna have to remove the door panel, just screws and clips that need a tug to pull them out. Then check your "regulator" or the tracks that the window goes up and down on, sometimes little pieces of dirt and plastic get in the tracks and seize up the window

I just pulled my amp apart and #2 is exactly where mine looks bad. Everything else on the amp looks fine. Did it work when you soldered at #2?

get an ohm meter and measure resistance between pins that should be connected through the copper tracks. Resistance should be low; if it's not, get wire and connect them directly. Make sure your soldering is nice. Shinny. If you can not do that, find an electrician or somebody who knows what he is doing.
