in the Removal and Installation section of this group
for the procedures.
(2) Rotate the temperature control knob on the
heater-A/C control so that the knob pointer is in the
12 o'clock position.
(3) Pull the temperature control knob straight out
from the heater-A/C control base until the perimeter
of the knob (not the knob pointer) protrudes about 6
millimeters (0.25 inch) from the face of the control
base.
(4) Rotate the temperature control knob to the 1
o'clock position. Push in on the knob slightly and con-
tinue rotating the knob to its full clockwise stop. The
knob pointer should be aimed at a position about 8
millimeters (0.315 inch) beyond the end of the grad-
uated red strobe temperature control graphic on the
face of the heater-A/C control base. If the knob is not
pointed to the correct position, go back to Step 2 and
repeat the adjustment procedure.
(5) Rotate the temperature control knob counter-
clockwise until the knob pointer is in the 12 o'clock
position again.
(6) Push the temperature control knob straight in
towards the heater-A/C control base until the perim-
eter of the knob (not the knob pointer) is flush with
the face of the heater-A/C control base.
(7) Rotate the knob to its full clockwise stop again.
The knob pointer should be aimed at the end of the
graduated red strobe temperature control graphic on
the face of the heater-A/C control base. If OK, go to
Step 8. If not OK, go back to Step 2.
(8) Rotate the knob to its full counterclockwise
stop and release the knob. If the knob springs back
from the counterclockwise stop, the self-adjuster clip
that secures the temperature control cable to the
blend-air door lever is improperly installed. See Tem-
perature Control Cable in the Removal and Installa-
tion section of this group for the procedures. If the
knob does not spring back, the temperature control
cable adjustment is complete.
