Power Window/Sunroof

The central locking module controls the power supply to the power windows/sunroof circuits by an external relay. The power window/sunroof circuits are therefore powered according to U.S. specific coding. Windows and sunroof operation is possible with the ignition switch turned to position 1 (KLR). Window and sunroof operation remains possible after the ignition switch is turned off until either front door is opened.


More detailed information (including information on U.S. specific coding) is available in the E36 Electrical Troubleshooting Manual in the following sections:
