This may be due to water intrusion into the cooling fan relay, a loose ground connection, or damaged wiring. Before replacement of the cooling fan assembly, perform Pinpoint Test KN. Also, locate the cooling fan relay and inspect for water intrusion or damage. The correct location of the cooling fan relay is in the front right portion of the engine bay. If the cooling fan relay is not in the correct location, check behind the front right wheel well in between the splash shield. If any water intrusion or damage is found to the relay, G103, or the connector C1048, replace and correctly mount the affected component as necessary.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10199651-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10199651-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10199651","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer"]},{"make":"FORD","model":"EXPLORER POLICE INTERCEPT","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_explorer","2021_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
