Summary
After extended idling, the high-speed cooling fan relay may fail in some of the affected vehicles. A failure will cause the fan to either continuously run or never turn on. A continuously running fan will increase the temperature of the relayâs connections (terminals) to beyond their design maximum. This may eventually create an electrical arc which heats and damages the relay terminals. Customers may experience a drained battery and a non-functional or even a melted/burned high-speed cooling fan relay inside the battery junction box (BJB). A damaged non-functional relay causing the fan to never turn on, may lead to engine overheating at idle.

REASON FOR THIS PROGRAM
After extended idling, the high-speed cooling fan relay may fail in some of the affected vehicles. A
failure will cause the fan to either continuously run or never turn on. A continuously running fan will
increase the temperature of the relay’s connections (terminals) to beyond their design maximum. This
may eventually create an electrical arc which heats and damages the relay terminals. Customers may
experience a drained battery and a non-functional or even a melted/burned high-speed cooling fan
relay inside the battery junction box (BJB). A damaged non-functional relay causing the fan to never
turn on, may lead to engine overheating at idle.
SERVICE ACTION
Dealers are to replace (splice) the four affected high-speed cooling fan relay terminals in the BJB and
reroute the new terminals to a new larger relay. This service must be performed on all affected
vehicles at no charge to the vehicle owner.
OWNER NOTIFICATION MAILING SCHEDULE
Owner letters are expected to be mailed the week of September 06, 2021. Dealers should repair any
affected vehicles that experience high-speed cooling fan relay issues that arrive at their dealerships,
whether or not the customer has received a letter.

away from an authorized servicing dealer after the date of the Owner Notification Letter. Noncovered repairs, or those judged by Ford to be excessive, will not be reimbursed.

related issue.

REPLACED FSA PARTS INSPECTION AND SIGN OFF
Effective March 1st 2021 all parts replaced as part of an FSA repair with a repair order open date of
March 1st 2021 or later must be inspected and signed off on the repair order by a member of your
dealers fixed operations management team or an employee the task has been delegated to. If the
task is to be delegated to a non-management employee, the employee needs to be someone other
than the technician who completed the repair and needs to understand the importance of completing
this task consistently and accurately.
•
All parts replaced as part of an FSA repair should be returned to the parts department
following the Warranty Parts Retention and Return Policies.
•
Inspect the replaced parts to verify the FSA repair was completed.
•
If the FSA repair is found to be complete, the designated employee signs the repair order line
or parts return stamp area (electronic or hand signed) for the FSA repair indicating the parts
were inspected and validated to have been replaced.
•
After the parts have been inspected, they should be handled based on the guidance in the
parts status report in the Online Warranty System (Hold, Return, CORE, Scrap, etc.).
•
This process is subject to review during warranty audits for FSA repairs with a repair order
open date of March 1st 2021 or later. Any eligible FSA claims requiring parts replacement,
found not to have been inspected and signed off during a warranty audit will be subject to
chargeback and consideration for enrollment into the Dealer Incomplete Recall Repair
Process.
Note: Other approvals (electronic or handwritten) for add-on repair lines, dealer owned vehicle
repairs, and repeat repairs do not qualify as FSA parts inspection approvals. The post repair FSA
parts inspection process (electronic or handwritten) is independent from other warranty approval
requirements. The approval by the designated employee implies that the FSA parts were found to be
replaced and must be able to be clearly identified on the Repair Order. If multiple FSA’s require
approval on a single Repair Order, each applicable occurrence will require individual post repair
approval by the designated employee.
