WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

CHECK REAR POWER WINDOW SWITCH (RH) OUTPUT SIGNAL

Turn ignition switch OFF.
Disconnect rear power window regulator (RH).
Turn ignition switch ON.
Check voltage between rear power window switch (RH) connector D72 terminal 1 and 2.

CONNECTOR TERMINAL VOLTAGE

Connector	Terminals (Wire color)		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
D72	1 (G)	Ground	Closing	0
	1 (G)		Opening	Battery voltage
	2 (L)		Closing	Battery voltage
	2 (L)		Opening	0

OK or NG

OK : Replace rear power window motor (RH).
NG : GO TO 2.
