Power Windows
The driver can control all of the power windows from the Driver Door Module (DDM) while each passenger can control their own power window from the power window switch in their respective door. The DDM also has a lockout switch that prevents power window operation from the power window switch in each passenger door. When in lockout mode, the lockout switch illuminates in red and each passenger window switch LED turns off indicating the respective switch is inactive. Another feature allows power window operation to continue from any power window switch for 45 seconds after turning off the ignition, but only if the front doors remain closed. Still another power window feature is the Express Down feature. This feature works on all four windows and is activated by pressing the power window switch into the second detent. Once activated, the operator can release the power window switch and the power window will travel to the full open position. To stop the Express Down feature, momentarily pull the switch in the up direction.
When a rear seat passenger actuates a rear power window switch, the respective door module, DDM or PDM, receives a multiplex signal. In turn, the door module supplies 12 volts and ground, in the appropriate direction, to the up and down window motor circuits of the respective rear door power window.
