Condition
Some customers may comment on one or more of the following concerns:
• Temperature control inoperative
• No heat
• No defrost
Cause
This condition may be caused by the air conditioning evaporator case not aligning with
the upper HVAC housing case, causing the control gears not to engage properly when
adjusting the temperature.
Correction
1. Check the temperature and mode cables operation as instructed in Service Bulletin
17-NA-113 (Document ID# 4694428).
⇒ If the gear mesh is lost during adjustment, replace the air conditioning
evaporator case.
2. With the cable detached, verify that the mode and/or temp doors move freely.
⇒ If the doors are sticking with the cables detached, replace the air
conditioning evaporator case.
Note: When replacing the case, a new cable retention feature has been added to
prevent kinking of the cable.
