Normal Operation
Voltage is supplied to the passenger front window control switch from the driver window control switch through circuit 170 (RD/LB). If the driver window control switch is in the lock position, the circuit is open and the window does not operate from the passenger front window control switch.

When operating the passenger front window in the down position, ground is received from the driver window control switch through circuit 313 (WH/YE). Voltage is supplied to the passenger front window motor through circuit 333 (YE/RD) and ground through circuit 334 (RD/YE).

When operating the passenger front window in the up direction, ground is received from the driver window control switch through circuit 314 (TN/LB). Voltage is supplied to the passenger front window motor through circuit 334 (RD/YE) and ground through circuit 333 (YE/RD).

When the passenger front window is operated in the down direction from the driver window control switch, voltage is sent to the passenger front window control switch through circuit 314 (TN/LB), which transfers voltage to the passenger front window motor through circuit 333 (YE/RD). Ground is provided to the RH front window control switch through circuit 313 (WH/YE), which transfers ground to the passenger front window motor through circuit 334 (RD/YE). When the passenger front window is operated in the up direction from the driver window control switch, voltage is sent to the passenger front window control switch through circuit 313 (WH/YE), which transfers voltage to the passenger front window motor through circuit 334 (RD/YE). Ground is provided to the passenger front window control switch through circuit 314 (TN/LB), which transfers ground to the passenger front window motor through circuit 333 (YE/RD).

Possible Causes
- circuit 170 (RD/LB) open
- circuit 313 (WH/YE) open
- circuit 314 (TN/LB) open or short to ground
- circuit 333 (YE/RD) open or short to ground
- circuit 334 (RD/YE) open
- passenger window regulator motor
- passenger front window control switch
- driver window control switch
