Power Window Switch - Operation

OPERATION

The driver side front door power switch module combines a power lock switch, a power window switch for each of the four door windows including auto-down (also known as one-touch down or express down) and express up features for both front door windows, a power window lockout switch, a power mirror selector switch, and a power mirror adjustment switch in a single unit. The passenger side power door switch module combines a power lock switch and a passenger side front door power window switch with the auto-down and express up features.

The driver side front door power switch module provides resistor multiplexed outputs to the driver door module indicating the power lock switch selection, hard wired analog outputs indicating the power mirror selector switch and adjustment switch selections, and electronic message outputs over a Local Interface Network (LIN) data bus connection indicating the power window switch selections. The passenger side front door power switch module provides resistor multiplexed outputs to the passenger door module indicating both the power lock and power window switch selections.

The hard-wired circuits between the driver side front door power switch module and the driver side door module or the rear door power window switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the electronic controls and communication between the switch module and the door module or in the diagnosis of the electronic controls and communication between other modules and the door module that provide some features of the power lock, power mirror or power window systems. The most reliable, efficient, and accurate means to diagnose the driver side power switch module or the electronic controls and communication related to power lock, power mirror or power window system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
