Passenger Windows

Voltage is applied to the power window relay at all times through fuse 3 (in the under-dash fuse/relay box). With the ignition switch in ON or START, ground is provided to the coil of the power window relay. The contacts of the power window relay then close, applying voltage to the individual window switches and the power window master switch. With the main switch ON, the passenger windows can be operated from the individual window switches or from the power window master switch.

When you push the front passenger's power window switch to UP, voltage is applied to the front passenger's power window motor. (The motor is grounded through the contacts in the front passenger's power window switch and the power window master switch.) The window moves up as long as you hold the switch in the UP position. If you push the switch to DOWN, voltage is applied in the opposite direction to the front passenger's power window motor, and the window moves down as long as you hold the switch in the DOWN position. The window switches in the other doors operate similarly.

When you push the front passenger's power window switch in the power window master switch to UP, voltage is applied through the front passenger's power window switch contacts to the front passenger's power window motor. (The motor is grounded through the contacts in the front passenger's power window switch and the power window master switch.) The window moves up as long as you hold the switch in the UP position. If you push the switch to DOWN, voltage is applied in the opposite direction to the front passenger's power window motor, and the window moves down as long as you hold the switch in the DOWN position. The other passenger window switches in the power window master switch operate similarly.
