TECHNICAL SERVICE BULLETIN
SUBJECT:
A/C EVAPORATOR FREEZE-UP DURING EXTENDED DRIVE
This bulletin provides the procedure to replace the evaporator temperature sensor of some
Optima (TF/QF) and Sorento (XMa) vehicles (see production dates on Page 3), which may
experience freezing of condensation on the evaporator core and the following A/C performance
related concerns:




Increased cabin temperatures after a long period of highway driving
Lower volume of air flow felt coming out of the vents
Increased noise from the blower motor due to restricted airflow across the evaporator
Small particles of ice or water vapor seen exiting from the dashboard vent
NOTE: Switching from Recirculation Mode to Fresh Air Mode or parking for several
minutes may restore normal A/C operation, for a period of time.
These conditions occur more often in extremely hot and humid climates (Texas, Florida,
Louisiana, Arkansas, Missouri, etc.). In the event a customer complains about any of these
specific conditions, perform the procedure outlined in this bulletin to resolve the concern.
 NOTICE
Replacement parts will have a small blue line on the connector, as shown below.
