Ford Explorer 2003 - Pinpoint Test L: Passenger Rear Window Inoperative; L1 CHECK THE VOLTAGE TO THE PASSENGER REAR WINDOW CONTROL SWITCH

Pinpoint Test L: Single Power Window Is Inoperative — Passenger Rear Window
Normal Operation
Under normal operation the passenger rear window control switch receives power from the driver window control switch through circuit 170 (RD/LB). The passenger rear window control
switch provides power to the power window motor through circuit 882 (BN/YE) and ground through 881 (BN) to operate the passenger rear window down, and power through circuit 881
(BN) and ground through 882 (BN/YE) to operate the passenger rear window up.
When operating the passenger rear window using the driver window control switch, power is sent to the passenger rear window control switch through circuit 320 (RD/BK) and ground
through 319 (YE/BK) to operate the passenger rear window down, and power through circuit 319 (YE/BK) and ground through 320 (RD/BK) to operate the passenger rear window up.
Possible Causes
 Open in circuits 170 (RD/LB), 319 (YE/BK), 320 (RD/BK), 881 (BN) or 882 (BN/YE).
 Inoperative driver window control switch.
 Inoperative passenger rear window control switch.
 Inoperative passenger rear window motor.
PINPOINT TEST L: SINGLE POWER WINDOW IS INOPERATIVE — PASSENGER REAR WINDOW
 Connect a jumper wire between driver rear window control switch C701-1, circuit 316 (YE/LB)
and C701-2, circuit 885 (YE/LB) and a second jumper wire between C701-3, circuit 170
(RD/LB) and C701-5, circuit 884 (YE/BK) harness side. The window should operate in the
upward direction.
 Does the window operate correctly?
K5 CHECK CIRCUITS 884 (YE/BK)/881 (BN) AND 885 (YE/LB)/882 (BN/YE) FOR AN OPEN
 Ignition OFF.
 Disconnect: Driver Rear Window Motor C703.
 Measure the resistance between driver rear window control switch C701-5, circuit 884
(YE/BK) and driver rear window motor C703-2, circuit 882 (BN/YE) harness side.
 Measure the resistance between driver rear window control switch C701-2, circuit 885
(YE/LB) and driver rear window motor C703-1, circuit 881 (BN) harness side.
 Are the resistances less than 5 ohms?
Yes
INSTALL a new driver rear window motor. REFER to Window Glass — Rear
Door in this section. TEST the system for normal operation.
No
REPAIR circuit 884 (YE/BK)/881 (BN) or circuit 885 (YE/LB)/882 (BN/YE).
TEST the system for normal operation.
