Just noticed this issue - I roll the windows down often, but always from
drivers console. They all work fine this way. My son tried to roll the
window down and back up from passnger (front) seat. The window went down
(would not go all the way down automatically like the rest do) but when he
pressed up, it kept going down. I played with it some; same thing.
Hopefully just the switch? Anyone seen this before?
Probably some shit in the channels/guides. Does it work with your switch? If
so it could be the switch but the stop go wind down is akin to the safety
feature of stopping your kid strangulating himself winding up the window with
his head in the opening.
No, it works correctly (completely) from drivers switch... only manual donw
(when rocking either direction from passenger side). Seems like a switch
since it works from the otherside.
Someone told me to try rolling all the way down and hold it for 10 secs,
the all the way up and hold it for 10 secs - no change.
Are the switches hard to get out?

There won't be as the controller already knows where the window is on it up and
down because it stops at the top and bottom. Look at the switch to start with -
try swapping for another like the opposite side switch first.
I popped the switch out and swapped it with one of the rear switches... the
problem did NOT follow the switch. It appears to be something in the
wiring, relay, or controller. Anyone know which relay I should check for
the passenger front window (controlled by the passenger switch)? Any other
Now I know you have a BMW and I am going to start talking about a UK ROVER but
please bear with me.
Being somewhat as a past expert on the foibles of ROVER electrics......... Can I
Somewhere in your car (ask the dealer or look on the EWD CD if you have one (if
not I can sell you one)) there is an electronic control unit that has all the
chips and memory functions of the roof and windows.
The ROVER had it under the left front seat. The game with the Rover was to
remove the box, open it, re solder all the joints, reassemble and screw back
into the car.
However another problem was the wiring connectors in/under the side front and
rear B pillar corroding and giving a bum signal to the control unit.
Might be worth investigating. the Rover at the front end need the fenders/wings
un-bolted to get at the connectors whereas the B pillar ones were hidden under
the carpet and stuffed into the base of the B pillar.
Check it out.
Could be affecting my power seat and steering wheel issue too (maybe?) - Is
it pretty easy to get to? I guess I remove the plastic tray below the
glove box and drop the box down? Any other tips?
I removed all the lower covers and trim off the other side in an attempt to
trouble shoot the steering wheel motors.
I removed the glove box and unplugged the "general module"... the module
and connectors all looked fine. With it unplugged, I could still use the
windows and they worked the same.
I did notice that I could put a fuse in the drivers seat and steering wheel
adjustment (was blowing before) with the module unplugged. When I plugged
the module back in, the steering wheel moved for a minute then the fuse
I ordered the Bentley manuals, hopefully I can track down more to test with
a wiring diagram.
