Power Window Master Switch Input Test

NOTE: The power window control unit is built into the power window master switch.

Remove the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT ).
Disconnect the 22P connector (A) from the power window master switch (B).

Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
- If the terminals look OK, go to step 4.

Reconnect the connector to the power window master switch, turn the ignition switch to ON (II), and do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.

If all the input tests prove OK, go to step 5.

POWER WINDOW MASTER SWITCH VOLTAGE REFERENCE CHART

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
1	BLK	In all ignition switch positions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground(G501) An open or high resistance in the ground wire
14	BLK	In all ignition switch positions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G501) An open or high resistance in the ground wire
4	ORN	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. B3 (20 A) fuse in the under-dash fuse/relay box An open or high resistance in the wire
5	BRN	Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Blown No. B17(20 A) fuse in the under-dash fuse/relay box An open or high resistance in the wire
22	RED	Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Faulty power window master switch An open or high resistance in the wire
16	BRN	Under all conditions	Check for continuity to ground: There should be continuity.	Poor ground(G501) Faulty power window master switch An open or high resistance in the wire
17	YEL	Ignition switch ON (II), and driver's window switch moving up or down.	Measure the voltage between the terminals No. 16 and No. 17: There should be 0 V - about 5 V - 0 V - about 5V repeatedly (a digital voltmeter should read about 2.5 V while the window moves).	Faulty power window master switch Faulty driver's power window motor An open or high resistance in the wire A short to ground in the wire
18	BLU	Ignition switch ON (II), and driver's window switch moving up or down.	Measure the voltage between the terminals No. 16 and No. 18: There should be 0 V - about 5 V - 0 V - about 5 V repeatedly (a digital voltmeter should read about 2.5 V while the window moves).

Turn the ignition switch to LOCK (0), then disconnect the 22P connector from the powerwindow master switch again.

With the connector still disconnected, do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.

If all the input tests prove OK, replace the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT ).

NOTE: After replacing the power window master switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
2	LT BLU	Connect the terminals No. 4 and No. 2 and the terminals No. 3 and No. 1 with jumper wires	Check driver's power window motor operation: The window should go up.	Faulty driver's power window motor Faulty driver's power window switch An open or high resistance in the wire
3	PNK	Connect the terminals No. 4 and No. 3 and the terminals No. 2 and No. 1 with jumper wires	Check driver's power window motor operation: The window should go down.
7	WHT	Ignition switch ON (II), connect the terminals No. 7 and No. 5 and the terminals No. 6 and No. 14 with jumper wires	Check passenger's power window motor operation: The window should go up.	Faulty passenger's power window motor Faulty passenger's power window switch An open or high resistance in the wire
6	YEL	Ignition switch ON (II), connect the terminals No. 6 and No. 5 and the terminals No. 7 and No. 14 with jumper wires	Check passenger's power window motor operation: The window should go down.
