The auto open function on the driver's and passenger's side power window is inoperative.

POSSIBLE CAUSE

• No power supply to power window main switch

• Power window main switch malfunction (power window control unit malfunction, auto switch malfunction)

• Power window motor malfunction

• Malfunction in wiring harness between power window motor and power window main switch

STEP

INSPECTION

ACTION

1

• Turn the ignition switch to ON position.

• Operate driver and passenger side power window using automatic open function on the power window main switch.

• Do each side power window open normally?

Yes

The power window system is normal.

No

Automatic open function does not operate both sides:

• Go to the next step.

Automatic open function does not operate one side:

• Go to step 4.

2

• Turn the ignition switch to ON position.

• Measure the voltage between power window main switch following terminal and ground.

• Terminal 1B (power retractable hardtop model)

• Terminal I (soft-top model)

• Is the voltage B+?

Yes

Go to the next step.

No

Repair or replace for open circuit.

3

• Turn the ignition switch to LOCK position.

• Disconnect the power window main switch connector.

• Verify that the continuity between following power window main switch terminal and ground.

• Terminal 1G (power retractable hardtop model)

• Terminal J (soft-top model)

• Is there continuity?

Yes

Inspect the power window main switch.

(See POWER WINDOW MAIN SWITCH INSPECTION.)

(See POWER WINDOW MAIN SWITCH INSPECTION[POWER RETRACTABLE HARDTOP].)

Replace the power window main switch if necessary.

No

Repair or replace for open circuit.

4

• Turn the ignition switch to ON position.

• Operate suspected side power window using manual open function on the power window main switch.

• Do suspected side power window open normally?

Yes

Replace the power window main switch. (power window control unit malfunction)

(See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)

No

Go to the next step.

5

• Turn the ignition switch to LOCK position.

• Disconnect the power window main switch and suspected side power window motor connector.

• Inspect for poor connection (such as damaged/pulled-out pins, corrosion etc.)

• Is there any malfunction?

Yes

Go to the next step.

No

Repair or replace malfunctioning part.

6

• Inspect for open or short circuit in wiring harness between suspected side power window motor and power window main switch.

Power retractable hardtop model driver's side:

• Terminal 1I (main switch)—terminal G (motor)

• Terminal 1J (main switch)—terminal A (motor)

Power retractable hardtop model passenger's side:

• Terminal 1D (main switch)—terminal G (motor)

• Terminal 1F (main switch)—terminal A (motor)

Soft-top model driver's side:

• Terminal G (main switch)—terminal G (motor)

• Terminal B (main switch)—terminal A (motor)

Soft-top model passenger's side:

• Terminal A (main switch)—terminal G (motor)

• Terminal D (main switch)—terminal A (motor)

• Is the open or short circuit detected?

Yes

Repair or replace for open or short circuit.

No

Go to the next step.

7

• Inspect suspected side power window motor.

  (See POWER WINDOW MOTOR INSPECTION.)

• Is the power window motor normal?

Yes

Replace the power window main switch. (power window control unit malfunction, auto switch malfunction)

(See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)

No

Replace the power window motor.
