Applicability
Introduction
Some RAV4 vehicles with manual air conditioning Systems may exhibit a condition where the HVAC system intermittently blows warm air from the
vents with the A/C on.
Diagnostic Trouble Code (DTC) B1479 (Flow Sensor Circuit) may be stored in the A/C system as a current code. A malfunctioning A/C compressor
flow sensor may cause this condition. Follow the procedure in this TSB to repair the vehicle.
NOTE
Manual A/C Systems do not have the ability to store history DTCs, therefore DTC B1479 may not be present even when the flow sensor is
malfunctioning.
