If the radiator fan and/or the condenser fan of the vehicles listed below runs continuously; or, if the fan(s) runs continuously when the engine is off, the battery may be discharged.

APPLIES TO:
2000 3.2 TLs – from VIN 19UUA5…YA000001 through VIN 19UUA5…YA057139; and 2001 3.2 CLs – from VIN 19UY4A…1A000001 through VIN 19UYA4…1A015025.

PROBABLE CAUSE:
The radiator and/or condenser fan relay has failed.

CORRECTIVE ACTION:
Replace both relays. If one relay fails, you must replace both.

PARTS INFORMATION:
Relay assembly (two required): P/N 39794-S0K-A01.

DIAGNOSIS:
• If the battery is discharged, and there is no apparent reason, remove the radiator fan and condenser fan relays from the underhood fuse/relay box, and shake them one at a time. If you hear a rattle coming from either relay, go to the Repair Procedure.
• If the fan(s) runs continuously with the ignition switch off, install known-good relay(s) and verify that the fan(s) stops. If the fan(s) stops with the known-good relay(s), go to the Repair Procedure.
Note: If the coolant temperature is high (above 185° F) when the ignition is switched off, the fan(s) will automatically run for about 15 minutes.
• If the battery is discharged and the relay(s) are OK, troubleshoot other causes.

REPAIR PROCEDURE:
1. Remove and replace the radiator fan and condenser fan relays in the underhood fuse/relay box. Refer to page 10-15 of the 1999-2001 3.2 TL service manual or page 10-13 of the 2001 3.2 CL service manual.
2. Turn off the A/C, start the engine and let it warm up. Make sure the fans cycle on and off when the engine reaches normal operating temperature.
