Power Window Master Switch Description

The power window master switch can control the UP/DOWN function of all the power windows. This is accomplished by wiring the power window master switch in series with the individual power window switches and motors. We'll use the RH power window for an example. Ground is supplied from G202 through CKT 150 (BLK) to connector C2 cavity C of the power window master. The internal circuitry of the power window master switch has this ground at the normally closed contacts of the master window switch to connector C2 cavity H and into CKT 170 (LT GRN) and connector C1 cavity H and into CKT 171 (PPL). These circuits connect to the RH power window switch at cavity E for CKT 170 (LT GRN) and cavity A for CKT 171 (PPL). With the HR power window switch in the at rest position, the normally closed contacts allow ground to the RH power window motor through CKT 670 (DK BLU) and CKT 671 (BRN). Since both sides of the RH power window motor are grounded, placing the power window master switch for the HR window in the DOWN position, voltage will be applied to CKT 171 (PPL) from CKT 343 (YEL) through the closed contacts of the switch and the RH power window goes DOWN. By placing the power window master switch for the RH window in the UP position, voltage will be applied to CKT 170 (LT GRN) from CKT 343 (YEL) through the closed contacts of the switch and the RH window goes UP.
The example used above for the RH window is the same for any other window in the vehicle, however, the circuit numbers and wire colors change between windows.
