2023 F-Super Duty - Buzzing Noise From Wireless Accessory Charging
Module (WACM) Cooling Fan
Some 2023 F-Super Duty vehicles equipped with a wireless charging pad may exhibit an excessive buzzing
noise from the WACM cooling fan. This may be due to the wiring harness or electrical tape contacting the
cooling fan. Remove the WACM and inspect for contact between the wiring harness and the WACM cooling
fan. Refer to Workshop Manual, Section 414-06. If contact is found, reroute the wiring harness away from
the WACM cooling fan to eliminate the noise. Use the Report a Vehicle Concern link at the bottom of OASIS
to submit a report with photos attached (if possible) if contact is found between the wiring harness and the
fan.
