Master Switch Input Test

NOTE: The control unit is built into the power window master switch, and only controls driver's door window operations.

Remove the driver's armrest, and disconnect the 16P and 1P connectors from the master switch.

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, make the following input tests at the connector.
- If a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the power window maser switch must be faulty; replace it.

TEST CONDITION CHART

Cavity	Wire	Test condition	Test: Desired result	Possible cause if result is not obtained
A4	BLK	Under all conditions	Check for continuity to ground: There should be continuity.	Poor ground (G551) An open in the wire
B1	BLK	Under all conditions	Check for continuity to ground: There should be continuity.	Poor ground (G551) An open in the wire
A3	BLU/BLK	Ignition switch ON (II)	Check for voltage to ground: There should be battery voltage.	Blown No. 7,8,10 or 11 (20 A) fuse in the under-dash fuse/relay box Faulty power window relay An open in the wire
A2	GRN/BLK
A8	YEL/BLK
A15	RED/WHT
A7	RED/BLU	Connect the BLU/BLK terminal to the RED/YEL terminal, and the RED/BLU terminal to the BLK terminal, then turn the ignition switch ON (II).	Check the driver's window motor. It should run (the window moves down).	Faulty driver's window motor An open in the wire
A5	RED/YEL			Faulty driver's window motor An open in the wire
A1	BLU/YEL	Connect the GRN/BLK terminal to the BLU/YEL terminal, and the BLU/ORN terminal to the BLK terminal, then turn the ignition switch ON (II).	Check the front passenger's window motor: It should run (the window moves down).	Faulty front passenger's window motor Faulty front passenger's window switch An open in the wire
A11	BLU/ORN
A9	YEL	Connect the YEL/BLK terminal to the YEL terminal, and the YEL/GRN terminal to the BLK terminal, then turn the ignition switch ON (II).	Check the right rear motor: It should run (the window moves down).	Faulty right rear window motor Faulty right window switch An open in the wire
A10	YEL/GRN
A14	GRN/YEL	Connect the RED/WHT terminal to the GRN/YEL terminal, and the GRN terminal to the BLK terminal, then turn the ignition switch ON (II).	Check the left rear motor: It should run (the window moves down).	Faulty left rear window motor Faulty left rear window switch An open in the wire
A16	GRN
A6	BLU	Connect the BLU/BLK terminal to the RED/YEL terminal, and the BLK terminal to the RED/BLU terminal, then turn the ignition switch ON (II).	Check for voltage between the BLU and BLK terminals: Approx. 6 V should be indicated as the driver's window motor runs.	Faulty pulser Faulty driver's window motor An open in the wire
A4	BLK
