Passenger's Side Door Wiring Connector Inspection

1. Open the passenger's side door.

2. Remove the door sill trim.





3. Remove the right cowl side trim.





4. Unclip the main wire harness from the connector cover. Cut the wire tie holding the MDO3/MDO4 connector wires to the connector cover. Remove the wiring connector cover mounting bolts (2EA) and then remove the cover.

5. Follow the MDO3/MDO4 connector wires up to the connectors, disconnect the connectors. The release for the top connector is on top, the release for the bottom connector is on bottom.





6. Release the 4 door wiring harness connector locking clips by pressing them one at a time, working around the connector. Push the connector out of the body hole.





7. Inspect the removed connectors for corrosion and dirt.





8. If connectors are not corroded or are just slightly corroded, use an electrical contact cleaner to flush the connectors until they are clean. Flush the door side of the connector clean as well.

WARNING:
Protect the inside of the vehicle so the contact cleaner will not splash onto the trim.

9. Inject connector grease into each opening of the female connector terminal on the floor wire harness side.

Recommended Grease:
GREASE - NYOGEL 760G
P/N 00305-F0000-39

NOTE:
If the connector terminals have more than light corrosion, they cannot be cleaned, they must be replaced.

Proceed with passenger's side door wiring connector and door wiring replacement procedure as explained in the "Passenger's Side Door Wiring Connector and Door Wiring Replacement" section in this TSB.





10. Fit the grommet over the flange on the door wire harness connector. Apply a small amount of the clear sealant around the edges of the grommet as shown in the photo.





11. Carefully install the door wire connector back into the mounting hole. Be careful to keep the grommet in position.

NOTE:
If the grommet separates from the connector, remove the connector, refit the grommet in position, reapply a small amount of sealant to the grommet, and reinstall the connector.





12. Reconnect the door wiring connector.

13. Install the wiring connector cover.

14. Re-clip the main wire harness in the connector cover slip.
