Left Window Operation

When the left window UP switch is pressed voltage is applied from left door switch assembly terminal A (connector C2) through the UP contacts to terminal D (connector C1), through CKT164 to terminal A of the left window motor. See WIRING DIAGRAMS  . The motor is grounded to G301 through CKT 965, the left express down window module, CKT 165, the DN contacts to terminal B (connector 2) of the left door switch assembly, and CKT 804. The motor runs to drive the window up.

If the DN switch is held for less than 0.3 seconds, voltage is applied to the left window motor through the same CKTs but in the opposite direction. Voltage is now applied through the DN contacts, and the motor is grounded through the UP contacts in the left door switch assembly. The motor runs briefly to drive the window down. If the DN switch is held for more than 0.3 seconds the express down feature will be activated.
