.

CIRCUIT OPERATION

• When the power window switch is operated, sig-

nal is sent to the convertible top control module in 
order to operate the quarter window regulator 
motor to open/close the quarter window.

.

TECHNICAL DESCRIPTION (COMMENT)

• The cause may be a malfunction of the quarter 

window regulator motor <LH> drive circuit.

.

TROUBLESHOOTING HINTS

• Malfunction of the convertible top control module.

• Malfunction of the quarter window regulator 

motor assembly <LH>. 

• Damaged harness wires or connectors.

.

DIAGNOSIS

STEP 1. Check harness wires between convertible top 
control module connector F-34 (terminals 10, 3) and 
quarter window regulator motor <LH> connector F-36 
(terminals 1, 2).
Q: Are there any damaged wires between convertible top 

control module connector F-34 (terminals 10, 3) and 
quarter window regulator motor <LH> connector F-36 
(terminals 1, 2)?
YES : Replace it, then go to Step 4.
NO :  Go to Step 2.

STEP 2. Check the quarter window regulator motor <LH> 
operation.
(1) Check that the motor runs smoothly when the battery is 

connected directly to the motor terminals. 

(2) Furthermore, check that the motor operates in reverse 

when the terminal connections are reversed. (Refer to 

P.42-39

.)

Q: Is the quarter window regulator motor <LH> damaged?

YES : Replace it, then go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the power window main switch continuity.
(1) Exchange the power window main switch with one in good 

condition to check that the quarter window glass operates 
properly. (Refer to 

P.42-54

.)

(2) If normal operates can not be seen, replace the convertible 

top control module. (Refer to 

P.42-145

.)

Q: Is the power window main switch damaged?

YES : Replace it, then go to Step 4.
NO :  Go to Step 4.

STEP 4. Check symptoms.
Q: Does the quarter windows open and close normally?

YES : This diagnosis is complete.
