This may be due to spread terminal/terminal pushout in wire harness 14290 and on the corresponding pins to the body control module C (BCMC). Before replacement of the BCMC, disconnect all connectors from the BCMC and check the BCMC pins and wire terminals for damage. Refer to Workshop Manual (WSM), Section 419-10. If spread terminals or terminal pushout is present, repair as necessary. Refer to Wiring Diagram, Cell 005 for repair procedures. Reconnect all connections to the BCMC as indicated by the procedure in the WSM. Test the function of the A/C to verify that it is blowing cold air.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10212959-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10212959-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10212959","components":[{"id":"visibility","name":"Glass, wipers and mirrors","parent":null},{"id":"hvac","name":"Heating and air conditioning","parent":null}],"codes":["P0645","P2CFC","P2CFD"],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator","2022_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
