DESCRIPTION & OPERATION
Note. On Z3, 323i, 323is, 5-series, 7-series and 8-series, information is not available at time of publication. Wiring diagrams may be available. See WIRING DIAGRAMS .
All models are fitted with power windows as a standard feature. The system consists of the following: one-touch function to lower and raise window, clamping protection during automatic raising of window, window lowering control which lowers window about 4 mm when opening door, and a comfort relay that makes it possible to operate power windows once after ignition has been switched off and door opened once, but not yet shut.

INITIALIZATION
Note. If power windows are not initialized, tip function is blocked and clamping protection is not activated.
Close all doors. Turn ignition switch to RUN position. Raise appropriate window and keep power window switch in UP position for about 5 seconds.
POWER WINDOW MOTOR
Remove power window motor. See POWER WINDOW MOTOR under REMOVAL & INSTALLATION. Secure power window motor gently in vise. Using fused jumper wires, briefly apply positive battery voltage to terminal No. 1 and negative battery voltage to terminal No. 2 at power window motor. (Scheme 2) Power window motor should operate. When polarity is reversed, power window motor should operate in opposite direction. If power window motor does not operate as described or is noisy, replace power window motor.

Removal & Installation
- If possible, lower power window. Disconnect negative battery cable. Remove door panelling. Pull off plastic sheet. Disconnect control module harness connectors. Remove control module retaining screws attaching control module to window motor. Remove control module.
- To install, replace control module "O" ring and attach control module to window motor. To complete installation, reverse removal procedure. After installation is complete, perform power window regulator initialization. See «INITIALIZATION»(/bmw/z3/e36-1995-2000/remont/windows/#power-windows__initialization) .
Remove door trim panel. Lower window about 12" (30 cm). Disconnect window motor electrical connector. Push clips aside. Hold door window and disconnect window lift arms. (Scheme 3) Twist and lift out door window. To install, reverse removal procedure. After installation is complete, perform power window regulator initialization. See INITIALIZATION.
Scheme 3
Note. On 2-door models, it may be necessary to remove power window motor control module to access window motor rivets. See POWER WINDOW MOTOR CONTROL MODULE (2-DOOR) .
Removal
- On 4-door models, remove window. See «WINDOW»(/bmw/z3/e36-1995-2000/remont/windows/#power-windows). On 2-door and convertible models, clamp door window at raised position using wooden wedges. On all models, remove door or side panel.
