ISSUE:
The temperature control knob may be difficult to turn on some vehicles. There may also be a low or no heat/cooling condition accompanied by poor
temperature modulation. This may be caused by the single cable temperature door operating system being used.
ACTION:
Replace the A/C Temperature Control Cable Assembly with a new pull/pull cable design. The new design cable will provide improved control of the
temperature door. Refer to the following Diagnostic and Replacement Procedures for details.
DIAGNOSTIC PROCEDURE
