how does the drivers side 4 button window switch actually work?
all 4 switches individually have 5 postions and 6 functions
position 1 - hard down
position 2 - light down
position 3 - at rest
position 4 - light up
position 5 - hard up
function 1 - makes the window go down until you let go
function 2 - makes the window go down all the way even if you let go
function 3 - makes the window go up until you let go
function 4 - makes the window go up all the way even if you let go
function 5 - stop the window from continuing down while on auto
function 6 - stop the window from continuing up while on auto
Are these functions governed by mechanical means in the switches at each position or are they governed by a simple computer/circuit board that works as a controller and only interprets the input from the switch itself and then carries out each function as it reads from the "human input device"?

The relays are the thing that hold a condition when activated ... flick will energize the relay and it will hold till the pinch regulator shuts off the motor and de-energizes the relay. When you hold the switch you send 12v to the motor and it partially overides the pinch protector.
The switch it self is simply on-off [I am tempted to say single pole, single throw, but can not confirm it]. The brains is in the relays. [long time ago, before valves and semi-conductors the electronic computer was just bunch of relays]

right on that makes a lot of sense, i havent looked at the fuses and relays for quite some time and since my fiance has the rx i probably wont get to for awhile but does anybody know exactly which relay control this?

Flick action does not work or lift&hold does not work?

Great thread!The RX is my wife's car.
I feel like an idiot when I ride in it because I can't work the windows.
I can make the window go all the way down and I can make up go all the way up.
I can't stop it inbetween either going up or down.
I stare at the glass intently going up and down but, my finger control is lacking.
This usually happens at a traffic light with a stationwagon full of kids watching.
They must assume I'm getting a ride to the insane asylum.
