REPAIR PROCEDURE:
This bulletin involves installing a radiator fan jumper wire assembly into the headlamp and dashwiring 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 fan is not damaged.
4.Pry out the two Christmas tree type retainers located on the lower radiator enclosurereinforcement.

5. Install the jumper wire assembly (p/n 052931 57AA) between the radiator fan and theheadlamp and dash harness:

B. Connect the original two-way black connector to the new mating connector installedin 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.
