Driver's side window fix w/o express down
Driver's side window fix w/o express down Ok so I did the autotrix version of the window mod with only user related problems - fixed after a good night's sleep. Now my passenger window seems like its going to fly through and shatter my t-tops! excellent performance.
My driver's side window motor is now the slow poke. I want to do this mod to my driver's side, express-down elimination preferred (my e-down has not worked for the past year or so, and i'd rather not have it return). If I were to buy another passenger side module from autotrix, will I see a similar boost in my driver's side window performance like I saw on the pass side? Or is the fault within the module itself?

The left window is wired differently because of the express down module. You'll have to bypass the module in order to do what you want. You can bypass the module by simply connecting the gray wire to the brown output wire at the express down module. Make sure you get the right brown wire - there are two of them. The one you want is pin D in the connector. The one you don't want is pin C in the connector and will have power whenever the ignition is on so it's easy to find with a test light or multimeter.

So I bypass the express down module as you described and the autotrix kit for the passenger's side is plug n play on the driver's side?

I don't know about plug and play but once the express down module is bypassed, the left window wiring works essentially the same as the right side. The two motor wires are brown and dark blue just like on the right side. The dark blue wire at the left switch is still the same but the wire that would be brown at the right switch will now be gray at the left switch.

it's that or get a new module but they arent cheap.

K so I got a module and the window wont work if the drivers side up (dk blue) wire and down (brown) wire to the motor are both connected to there correct wires. window will roll up or down if I disconnect the opposite directions wire from the motor but will still not express down which honestly i dont care if it does I just want it to roll up and down. could it be that my motors are not the newer style motors my old system didnt require a ground in the wiring and the 95 system does. anyone think if I ran a few relays to control up and down from the switch signal to get it to work right? almost seems like I need to alternate ground legs on the motor when its operating.

Perhaps you could go into greater detail about what you're doing. Are you trying to fix factory power windows in a 72 Camaro? Or are you trying to install a more recent power window setup into the older car?

Can somebody point out in this diagram precisely what to do?:.....

you can make it work I installed the passenger side kit in both doors and eliminated the thermal resistor in both motors. My windows rock.

To bypass edm using above diagram, pasted from another thread, credit to OP:
*removed brown wire 341 frm s208 to module (c on module)
*removed blue wire 164 frm s263 to module (a on module)
*spliced grey wire 1136 (e on module) to brown wire 165 (d on module)
Now you can essentially plug n play passenger side Autotrix kit EXCEPT the brown and blue wires you splice into no longer come from the switch, they come from the bypassed edm throught the door grommet. You will also need to determine your own routing for power and ground, I just spliced into power I had already installed on passenger side kit. You will no longer have express down but the window works so much better you probably won't miss it.
eta: now that I'm thinking about it, I suppose you could tap into the motor power wires where they leave the edm, I was already in the door to replace the motor so I just tucked the relays into the bottom of the door but the relays could be installed under the dash.
eta again: looking at diagram, you should be able to bypass edm just by cutting gray wire from switch and connecting it to brown wire to motor, then the autotrix kit would be plug n play (or possibly unnecessary since the edm is no longer limiting voltage) I didn't do it that way but if you are feeling brave you could give it a try.

I don't know what you mean by "a short and power" - power is good, a short is not.

FWIW to anyone else reading, I did perform this steps listed above to wire in a pair of store bought relays on the drivers side and it did work as advertised. I know have 2 fast windows (drv and pass) but no express down.
The ONLY tough part of all of this is figuring out where to stuff the relays in the door so that they fit and dont rattle around while driving!!

Is it possible to use a relay on the driver's side door and retain express down? I understand the wiring, I'm just wondering about the express-down module knowing when to stop. I'm guessing it senses resistance which wouldn't work with a relay.
