Manufacturer summary

Original wording in English

HVAC Stuck in Defrost Mode, DTCs B0248, B0268 or B0408 Set Condition/Concern Some customers may comment that the HVAC system is stuck in the defrost mode. When checking the vehicle for DTCs, the HVAC control module may report B0248, B0268 or B0408 set as current. Once the DTC(s) are cleared, the air delivery mode can be changed. This condition may be due to an actuator over-traveling or intermittently binding, causing the DTC(s) to set.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
