Normal Operation
The passenger front window control switch receives power from the accessory delay relay through circuit (R/LB). The passenger front window control switch provides power to the passenger front window motor through circuit (R/Y) and ground through circuit (Y/R) to operate the passenger front window DOWN; and power through circuit (Y/R) and ground through circuit (R/Y) to operate the passenger front window UP.
