ISSUE: Wire insulation may shrink away from terminals at three connectors of the 14290 wire harness. The 14290 wire harness is located on the left hand fender apron in the engine compartment. Shrinkage is caused by high ambient engine temperatures and grease filled connectors.

FIGURE 1:

ACTION: Check for exposed wire at the terminals and wrap with electrical tape if required. Refer to the following service procedure.

1. Check the wires where they exit the connectors and see if the insulation is present, Figure 1.

2. If the wires are exposed, remove the wires and terminals from the connector.

3. Wipe off the grease from the terminals.

4. Using air pressure, blow the remaining grease out of the connector.

CAUTION: DO NOT USE ANY DEGREASING SOLUTION BECAUSE IT COULD DAMAGE THE CONNECTOR.

5. Tightly apply electrical tape on the exposed wires.

6. Reinstall terminals in the connector.
