W/Power Top Operation
CIRCUIT OPERATIONNOTE: The power windows on this vehicle operate automatically in the down mode when the power top switch is activated.
The power window system on this vehicle utilizes a pair of external relays (2) and a window timer module located in the left door to control the operation of the windows when the power top is activated.
Power for the window timer module is supplied on circuit P5 or P6. The F21 circuit supplies power for the power window switches, and the contact side of the power window relays. Ground for the module is supplied on circuit Z1.
When the power top switch is activated circuit P6 for top UP, or P5 for top DOWN, sends a voltage signal to the window timer module. The window timer module then provides voltage to the coil side of the relays. This causes the normally OPEN contacts in the relays to CLOSE connecting power to the DOWN side of each window motor. All windows then operate in the DOWN mode for a pre-determined length of time.
