| SSM 50811 | 2022-06-01. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some 2020-2022 Explorer/Aviator vehicles may exhibit the A/C blowing warm air with DTCs P0645, P2CFC, and/or P2CFD present in the heating ventilation and air conditioning (HVAC) module. 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. |

| SSM 50106 | 2021-09-28. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM. Some 2020-2021 Explorer/Aviator vehicles may exhibit the A/C blowing warm air with DTC P0645 present in the heating ventilation and air conditioning (HVAC) module. 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).

| SSM 50015 | 2021-09-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; VISIBILITY; EQUIPMENT. Some 2020-2021 Ford and Lincoln vehicles are equipped with an anti-fogging feature known as enhanced windshield anti fogging strategy (EWAFS). This feature automatically adjusts airflow in the cabin to prevent the windshield from fogging up and may be perceived by customers as irregular climate control functionality. To reduce fogging, the EWAFS functions include: the air condition (A/C) button may turn on and off automatically, recirculated air may turn off automatically in all air modes except MAX A/C, recirculated air may also turn on and off automatically in various airflow modes in order to improve heating or cooling efficiency, and in auto climate control, high humidity conditions may automatically engage A/C compressor, increase blower motor speed and/or direct more air to windshield. Continue to monitor the Workshop Manual (WSM) for EWAFS updates. |
| SSM 49377 | 2021-01-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM. Some 2020-2021 Explorer/Aviator vehicles equipped with a 3.0L EcoBoost engine and built on or before 01-Dec-2020 may exhibit inoperative air conditioning, an illuminated malfunction indicator lamp, and/or an illuminated powertrain malfunction (wrench) indicator with various diagnostic trouble codes present and a blown fuse F14. This may be due to wiring harness 14290 chaffing on the A/C compressor pulley. If chaffing is present, repair as necessary. Refer to Wiring Diagram, Cell 005 for repair procedures. Make sure that the wiring harness retainer is fully seated in the back side of the bracket on the A/C compressor to keep the harness away from the compressor pulley. |
