To check the temperature cable adjustment, move the temperature control lever
all the way to the left, then move it all the way to the right. At the extreme
ends of lever travel, the door should be heard to firmly seat, indicated by
a loud thumping sound, allowing either maximum or no air flow through the
heater core. To check the function cable adjustment, see that the function
lever will reach the detents at the far left and right of its travel. In addition,
check that the air flow is correct when the function lever is moved through
each detent provided in the control assembly. If cable adjustment is needed,
proceed as follows:
- Disengage the glove compartment door by squeezing its sides together.
Allow the door to hang free.
- Working through the glove compartment opening, remove the cable jacket
from the metal attaching clip on the top of the plenum by depressing the
clip tab and pulling the cable out of the clip.
NOTE: The adjustable end should remain attached to the
door cams.
- To adjust the temperature control cable, set the temperature lever at
COOL and hold. With the cable end attached to the temperature door cam,
push gently on the cable jacket to seat the blend door. Push until resistance
is felt. Reinstall the cable to the clip by pushing the cable jacket into
the clip from the top until it snaps in.
- To adjust the function control cable, set the function selector lever
in the DEFROST detent and hold. With the cable end attached to the function
cam, pull on the cam jacket until cam travel stops. Reinstall the cable
to the clip by pushing the cable jacket into the clip from the top until
it snaps in place.
- Install the glove compartment.
- Run the system blower on HIGH and actuate the levers, checking for proper
adjustment.
- To adjust the temperature control cable (air mix): Set the temperature
control lever to the MAX-HOT position. Install the cable and secure the
attaching clip with the heater unit shutter lever all the way to the right.
Make sure the temperature control lever moves easily from the HOT to COLD
position.
- To adjust the airflow mode cable: Set the airflow mode control lever to
the DEFROST position. Install the cable and attaching clip with the heater
unit shutter lever at its closest point. Make sure the control lever moves
easily between the DEFROST and VENT positions.
- To adjust the rec/fresh control cable (air intake): Set the rec/fresh
lever to the RECIRCULATE position. Install the cable and attaching clip
with the blower unit shutter lever at its closest point. Make sure the control
lever moves easily from the RECIRCULATE to the FRESH position.
