VIN 667579 - 708757
ISSUE:
Cooling fans that are inoperative or operate while the ignition is switched off can be the result of corrosion in the cooling fan control module. The
corrosion is caused by water entering the ground wire cores and traveling inside the wire insulation to the module.
ACTION:
After repairing Sedan Range vehicle fans that were inoperative or operated with the ignition off, seal the ground wire eyelet connectors to prevent further
moisture from entering the cooling fan module. Use the following procedure.
NOTE
Ensure that the radio security code is available and record the preset radio stations (including X-mem) before disconnecting the battery ground cable.
SEALING COOLING FAN GROUND WIRES
1.
With the battery ground cable disconnected, disconnect the cruise control pump harness plug and the two ground eyelets on the left inner front
fender panel (illustration 1).
2.
Spread the two ground eyelets apart. Thoroughly clean and degrease the eyelets and wires.
3.
Cut a heatshrink sleeve (part number JLM 12166) in half. Fit one piece over the first ground eyelet (Illustration 2).
