Action Chart:

Step 3
1. Turn the ignition switch to OFF.
2. Disconnect the main switch assembly connector. 3. Check for continuity between the (B) terminal wire and ground.

Step 4
1. Turn the ignition switch to ON.

Voltmeter Connection:

Reference:

2. Measure the voltage at the terminal wires of the main switch assembly connector with the main switches in the following positions.
3. If correct, go to Step 5.
4. If not as specified, check the power window main switch assembly.
Step 5
1. Remove the passenger's and rear door trim.

Voltmeter Connection:

Reference:

2. Measure the voltage at the terminal wires of each subswitch connector with the main switches in the following positions.
3. If correct, go to Step 6.
4. If not as specified, repair the wiring harness (main switch assembly-subswitch).

Step 6

Voltmeter Connection:

Reference:

1. Measure the voltage at the terminal wires of each sub- switch connector with the main switches in the following positions.
2. If correct, go to Step 7.
3. If not as specified, check the power window subswitch.

Step 7
1. Remove the door screens.

Voltmeter Connection:

Reference:

2. Measure the voltage at the terminal wires of each regulator connector with the main switches in the following positions.
3. If correct, check the power window regulator.
4. If not as specified, repair the wiring harness (main switch assembly or subswitch-regulator).
