This repair group covers door glass, window regulator and
power window motor repair information.
CA U JIO&
All E39 models are equipped with side-impact airbags in the
front doors. Some models are also equipped with
airbags in
the rear doors. Be sure to read the
airbag warnings and cau-
tions in 721
Airbag System (SRS).
Electric window switch replacement is covered in 612
Switches.
The windshield, rear window, fixed rear doorglass, and cargo
compartment glass (Sport Wagon only) are bonded using
special adhesives and tools. It is recommended that bonded
glass replacement be done by an authorized
BMW service fa-
cility or an automotive glass installer.
Special tools
Some window repair operations require special tools.
Power windows
- Power window features in E39 models include:
Control of the front and rear door window motors is carried
out directly by the General Module (GM
Ill).
One-touch operation in both directions on all four windows.
Cable type window regulator used for all door windows.
. Anti-trap protection provided by pressure sensitive finger
guard.
Right front and each rear door has a single window switch
located in door handle trim.
Rear door window switches can be deactivated by press-
ing child lock-out switch in the driver's window switch block.
Convenience closinglopening of the windows from driver's
loci( cylinder or convenience opening only from remote un-
lociting feature (FZV) remote key.
Window (FZV) operation can be owner customized with
Car Memory function. See 515 Central Locking and Anti-
Theft.
After ignition is switched off, electric windows can be oper-
ated until a door is opened or until
I6 minutes has elapsed.
The GM
IiI bases window motor end position on current
draw (load). There is a maximum window motor run time of
6 seconds. The motor is then switched off even if the end
position load sensor fails.

Window switches
4 The push type window switch provides the GM Ill with a cod-
ed ground signal. Holding a switch at the first detent provides
a single ground signal on one wire requesting the GM
Ill to
open the window. When released, the ground signal is re-
moved and the window motor stops.
- Momentarily pushing the switch to the second detent and re-
leasing provides an additional ground signal on the second
wire requesting "one touch mode". The GM
Ill lowers the win-
dow automatically until it reaches the end position. Each win-
dow has four positions, two each for the standard mode of
operation and two for the one-touch mode. All window oper-
ation signals are digital inputs to the door modules and GM
111.
- The switch functions in the same manner for window closing
but the ground signal sequence is reversed.
4 Window switch positions.
1. Off
2. Open
3. One touch open
4. Close
5. One touch close
Rear window child lockout switch
4 The rear window child lockout switch (arrow) is incorporated
in the driver's window switch block in
leit front door arm rest.
When activated, it provides a constant ground signal to the
GM
Ill, preventing the windows from being operated from the
rear door switches.
- The lockout switch ground signal is overridden by the GM Ill
if a passive safety system (MRS) crash signal is received.

/ Anti-trap strip
Power window motors
The window motors are mounted on cable regulators. The
window motor control circuit consists of two wires for operat-
ing the motor in both directions.
The motors are activated by relays in the GM
Ill. The relays
provide either power or ground depending on the direction of
window travel. The GM
Ill controls the polarity based on a re-
quest to run the window from a window switch or a conve-
nience
openinglclosing signal.
Convenience openinglclosing
The GM Iii provides the convenience openlclose feature, pro-
viding control of the power windows (and sunroof) from out-
side the vehicle with the key in the driver's door lock. The FZV
(remote key) provides the same function for window opening
only.
Anti-trap protection is active during convenience closing from
the driver's door lock.
If the GM receives a request to operate convenience closing
or opening for more than
110 seconds, the function is deacti-
vated and a
fault code is stored.
Window anti-trap protection
4 A rubber pressure guard is located at the top edge of each
door frame. It consists of two contact strips that close when
subjected to pressure. When the contact strip closes (for ex-
ample, a hand is trapped between the top of the window and
the door frame), an anti-trap signal is sent to the GM
Ill. The
window immediately (within
10 milliseconds) reverses direc-
tion. This feature does not require
initialization.
The E39 pressure sensor finger guard has a resistance of 3
Kw and it is monitored for open circuits. When pressed, the
monitored resistance changes to
< 1 Kw. if anti-trap protection
becomes faulty the one touch window closing will not func-
tion.
Window anti-trap protection is
only active in the one touch
and convenience close modes of operation. If the window
switch is pulled and held, anti-trap protection will not function.
The anti-trap contact strip has a resistance of
1.2 K Ohm and
it is monitored for open circuits. Faults with the anti-trap sys-
tem will cancel the one touch feature requiring the window
switch be held to close the window.
