Affected Component: VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM

Summary
Some 2019-2020 Ranger vehicles built on or before 30-Jul-2020 may experience poor and/or no temperature change when the temperature is adjusted in the climate control system. There may also be a clicking/snapping noise from behind the instrument panel. Diagnostic trouble code (DTC) B1082 and/or B1081 may also be retrieved from the front controls interface module (FCIM). This may be due to an issue with the blend door and its controls. To avoid repeat repairs, replace the air distribution housing/heater assembly (service base part# 18478). Refer to Workshop Manual (WSM), Section 412-00. Do not replace the evaporator core for this condition. The WSM has been updated to reflect this change. For claiming use causal part 18478 and use applicable labor operations in Section 11 of the Service Labor Time Standards (SLTS) Manual.
