REPAIR PROCEDURE:

This bulletin involves installing a radiator fan jumper wire assembly into the headlamp and dash wiring harness, and replacing the solid state relay.

1. Raise the hood and disconnect the negative battery cable.
2. Raise the vehicle on a suitable hoist.
3. Locate the left (driver’s side) black fan motor connector. Retract the red latch on the two-way female connector, depress the thumb latch, and disconnect the connector from the fan (Figure 1). If the wiring to the fan motor is clipped into the fan support, gently pry it out of the hole so the fanis not damaged.
4. Pry out the two christmas tree type retainers located on the lower radiator enclosure reinforcement.
5. Install the jumper wire assembly (p/n 05293157AA) between the radiator fan and the headlamp and dash harness:
   1. Attach the black two-way male connector with the clip into the outboard hole, so the connector faces outboard toward the left side of the vehicle. Attach the second clip into the inboard hole of the lower reinforcement that the original wiring came out of (Figure 2).
   2. Connect the original two-way black connector to the new mating connector installed in the previous step and slide the red latch into the locked position.
6. Connect the two-way female black connector on the new jumper assembly to the fan connector and slide the red latch into the locked position. If the original wiring to the fan was clipped into the fan support, snap the new clip on the jumper into the same hole.
7. Bundle the excess original fan wiring and tie strap to the main bundle of vehicle wiring in the front left corner in two places. NOTE: ENSURE THAT THE WIRING BUNDLE IS SECURE AND DOES NOT INTERFERE WITH ANY OTHER COMPONENTS.
   
8. The solid state fan relay is located on the left front rail. Retract the red latch on the black four-way connector and disconnect from the solid state fan relay.
9. Remove the two screws that secure the relay to the side of the left front rail and remove the relay.
10. Install the new solid state fan relay ** (p/n 04707286)** and locate the index pin on the relay into the locator hole in the rail. Secure with the two screws and torque to 5 N•m (45 in.lbs.).
11. Connect the four way connector and slide the red latch into the locked position.
12. Lower the vehicle and connect the negative battery cable.
