51 2-2 I Door Windows 1 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 drivers window switch block. Convenience closinglopening of the windows from drivers 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.
51 2-3 Door Windows 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 drivers 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.
51 2-4 I Door Windows / 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 drivers door lock. The FZV (remote key) provides the same function for window opening only. Anti-trap protection is active during convenience closing from the drivers 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.
Door windows1 Window motor limit stop function If repeated window activation (upldown cycles) exceeds one minute, the GM Ill deactivates the internal relays and disre- gards any further upldown requests. The GM Ill provides mo- tor activation after a short duration but not for the full one minute monitoring cycle. The GM Ill monitors the number of times a window motor is activated. It counts each cycle and stores the number in memory. Afler the stop function limit is reached and the win- dow motor is deactivated, the GM Ill slowly reverses the stored count of activation until the stored number equals 0, thus allowing the window motor to cool down. WARNING- * Always wear hand and eye protection when working with brolen glass. If a window is brolen, all of the glass bits should be vacuumed out of the door cavity. Use a blunt so-ewdi-iv- er to clean out any remaining glass pieces from the window guide rails. When servicing the door windows, the harness con- nector to the window regulator should always be dis- connected to prevent pinching fingers in the moving window mechanism. Sedan and Sport Wagon doors are similar. Use the following procedures for window service on these models. WARNING- E39 cars are iitted with side-impact airbags in the front doors. Some are equipped with airbags in the rear doors as well. When servicing the door windows on cars with side-impact airbags, always disconnect the negative (-) battery cable. See 721 Airbag System (SRS) for cau- tions and procedures relating to the airbag system. * Prior to disconnecting the battery, read the battery dis- connection cautionsgiven 001 General Warnings and Cautions.
Door Windows Window anti-trap strip, testing - To test function of anti-trap strip on any window: With key ON and window down, pull up window switch to second detent, thus activating one-touch close operation. Insert wooden block or other soft object between glass and upper door frame. Window should contact block, then immediately reverse direction and lower by approximately 25 mm (1 in). NOTE- Anti-trap strip is integrated into the molding strip of the door window frame. Front window anti-trap strip, removing - Remove front door panel and vapor barrier as described in 411 Doors. < Remove window frame mold~ng strlp and peel toward inside 7 of vehrcle. Separate anti-trap electrical harness connector top front of door. NOTE- Wire color for anti-trap strip is dark gray. (arrow) at
