SUBJECT:
Power Door Lock Motor Whirling Noise

MODELS:
1996 - 1999 (NS) Town & Country/Caravan/Voyager

DISCUSSION:
Some front and/or sliding door power lock motors may make a whirling noise after the lock actuator has reached its full travel. Sometimes the wrong door power lock motor is replaced because of poor diagnosis procedures. The following diagnosis procedure is provided to help improve Fix It Right (FIR) scores.

1. With all vehicle doors open, activate the power door locks a minimum of five times repeatedly locking and then a minimum of five times repeatedly unlocking to discover any power door lock motors that make a whirling noise, even intermittently.

2. If a noisy power door lock motor is heard, determine which side is producing the whirling noise by placing your ear near the rear of the suspect front door, then activate the power door locks to confirm which side the whirling noise is coming from.

3. If the front door power lock motor/latch(s) is found to be noisy, Replace it using the procedures outlined on page 23-40 of the 1999 Town & Country, Caravan, & Voyager Service Manual.

4. If the whirling noise was not heard in step 1, close the left sliding door (leave the front doors open) and activate the door locks a minimum of five times repeatedly locking and then a minimum of five times repeatedly unlocking.

5. If the whirling noise is heard replace the left sliding door latch/lock control using the procedures outlined on page 23-52 of the 1999 Town & Country, Caravan, & Voyager Service Manual.

6. If the noise is not heard in step 4, open the left sliding door and close the right sliding door. (leave the front doors open) Activate the door locks a minimum of five times repeatedly locking and then a minimum of five times repeatedly unlocking.

7. If the whirling noise is heard replace the right sliding door latch/lock control using the procedures outlined on page 23-52 of the 1999 Town & Country, Caravan, & Voyager Service Manual.
