Principles of Operation

Window Operation

The window system operates under the control of the accessory delay relay. The smart junction box (SJB) will ground the coil side of the accessory delay relay when the ignition switch is in the ON position. When the accessory delay relay is active, power is supplied to each window control switch. The window control switches direct power and ground to the appropriate power window motor.

Window Control Switches

The windows can be operated from the LH front window control switch or from the window control switch located on each door trim panel. The LH front window control switch has 2 modes of operation for the LH front window, manual and auto. All other windows operate in the manual mode only.
Manual mode will move the window downward until the switch is released. The LH front window will operate in the manual mode when the LH front window control switch is pressed to the first detent position.
Auto mode provides the one-touch down (OTD) feature for the LH front power window. The OTD function allows the LH front window to be completely lowered when the LH front window control switch is pressed to the second detent position and then released. The OTD is controlled internally by the LH front window control switch.
The power window system will only operate if:

- the ignition is in the ON or ACC position or
- the accessory delay feature is in the active mode.

Rear Window Defrost

The dual automatic temperature control (DATC) controls the rear window defrost grid and heated mirrors (if equipped) by controlling the state of the rear window defrost relay. When the rear window defrost switch is pressed, the DATC will activate the rear window defrost relay. When the relay is active, both the rear window defrost grid and the heated exterior rear view mirror glass elements are energized.
The DATC will deactivate the rear window defrost relay when one of the following conditions is met:

- The rear window defrost switch is pressed when the feature is active.
- Ignition switch state is changed from ON to OFF/LOCK.
- The 15-minute timing function is complete.
