I just got done doing this to my '94. My circuit board was different than shown but it still worked. I looked for a picture of a diode on the silkscreen side (the side the components are on) but there was none. What I found was a couple of holes drilled through the circuit board. The holes looked like it was meant for a component to go there but none was there. The holes were drilled through so you could look at the traces(solder side) side of the board and find them. I connected my diode to the two pads (traces) where the holes were and pointed the diode toward the middle of the circuit board (line on diode toward the middle). It worked like a charm.

I then took off the rocker switch (promptly lost the circlip as it is really small) and filed down the stops. I was able to use a tiny wire to fashion an acceptable circlip.

A note about trying to get the window to stop in the middle. If you pull the rocker switch to full stops so it is in auto-up or auto-down mode you will not be able to stop the window in the middle. It will go to full extension. If you want the window in the middle you need to wait untill it has reached extension and then give it about 1.5 seconds...the logic in the circuit board then resets and you are now able to control it without it going full up or full down. Once at its stops you can control it either up or down in partials w/o it going into auto mode.

Easy mod. Thanks Lanktank.
