Attachment III - Technical Information

AFFECTED VEHICLES:
CERTAIN 1998 FORD CONTOUR AND MERCURY MYSTIQUE VEHICLES BUILT FROM JANUARY 1, 1998 THROUGH JUNE 1, 1998 AND CERTAIN 1999 MERCURY COUGAR VEHICLES BUILT FROM JOB # 1 THROUGH JUNE 1, 1998

OVERVIEW
When performing this service procedure, you will:

^ replace the existing wiring harness connector with a redesigned connector assembly

^ replace the existing blower resistor

^ verify the repair

SERVICE PROCEDURE

1. Remove the right-hand upper foot well trim panel pushpins and remove the panel (if equipped).





2. Remove the retaining screw and blower resistor and connector from the heater housing. See Figure 1.

CAUTION
Cut and splice only one wire at a time. The wire colors on the new blower resistor connector do not match the existing wiring harness colors.

3. Install the new blower resistor connector kit.

A. Obtain Blower Resistor Connector Repair kit # F5RZ-14A411-CA.

B. Select the first wire to be spliced from the switch wiring harness and cut it as close as possible to the blower resistor connector.

C. Select the corresponding wire from the new blower resistor connector.

D. Strip 1/4-inch insulation from the selected wires.

E. Install the appropriate splice connector using Crimp Tool # AD1522 or equivalent ratchet action crimp tool.

F. Test the integrity of all splices after crimping. Grasp the wires at each splice and pull gently. If any wire is not attached securely, replace the splice connector and crimp firmly.

G. Repeat steps B through F for the remaining wires, one at a time.





H. Heat each splice connector thoroughly until the tubing shrinks and adhesive flows from each end. Use Rotunda Heat Gun R07-10300 or equivalent. See Figure 2.

4. Install the new blower resistor.

5. Connect the new blower resistor connector to the new blower resistor.

6. Check operation of the blower motor.

7. Install the right-hand upper foot well trim panel (if removed).
