Cherokee Repair Procedure

1. Record the radio preset radio stations. Disconnect and isolate the battery negative cable.

2. Raise the vehicle on a hoist to gain access.

3. Locate a position on the upper cross member 3" (75 mm) from the left side and 2" down from the top edge. Then drill a 5/16" (8 mm) hole. This hole will be used for the guide pin on the solid state relay.





4. Position the solid state relay against the upper cross member with the guide pin in the hole. The relay will be parallel to the cross member. Scribe a mark on the cross member in the right and left mounting holes of the solid state relay. Remove the relay and drill two 9/64" (3.8 mm) holes in the cross member. Figure 4

5. Mount the solid state relay on the cross member using the two attaching screws in the parts package.

NOTE:
THE LOCATING PIN ON THE SOLID STATE RELAY MUST BE FULLY INSERTED INTO THE GUIDE PIN HOLE ALLOWING THE RELAY TO BE FLUSH TO THE CROSS MEMBER, OTHERWISE DAMAGE TO THE RELAY MAY OCCUR.

6. Disconnect the wiring connector from the radiator fan module.

CAUTION:
ON DUAL FAN MODULES, CARE SHOULD BE TAKEN TO INSURE THAT THE WIRING CONNECTION IS NOT MADE TO THE 2ND FAN MOTOR.

7. Connect the "Y" end of the wiring overlay harness from the parts package between the radiator fan module and the vehicle wiring harness. Connect the remaining connector to the solid state relay. Use tie straps as necessary to support the wiring overlay harness.

8. Route the single red wire from the wiring overlay harness to the Power Distribution Center (PDC) by following the vehicle wiring harness routing up the left side rail.

9. With the vehicle on the ground, remove the cover from the PDC and remove the starter relay, radiator fan relay and the A/C Clutch and Fog Lamp relays, if so equipped. Pry up on and remove the orange terminal locking strip.

10. Release the PDC from the battery tray by unlatching the two tabs along the front edge. Rotate the PDC over toward the left fender. Remove the plastic cover from the bottom of the PDC to allow access to the connectors.





11. Insert the terminal of the red wire from the wiring overlay harness into cavity # 12. This cavity is in the center of the radiator fan relay socket. Figure 5

12. Route the red wire along with the rest of the wire bundle and replace the plastic cover on the bottom of the PDC.

13. Rotate the PDC back into place on the battery tray.

14. Install the orange terminal locking strip back into the PDC and install the relays removed previously with the exception of the radiator fan relay.

15. Install the PWM module from the parts package into the radiator fan relay location in the PDC. Install the cover back on the PDC.

16. Connect the battery and reset the radio stations and clock.

17. Start the engine and with the A/C-Heater system in the defrost or A/C mode and recirculation mode and verify that the radiator fan(s) turn on.
