ADJUSTMENTS
The control cables are connected at the heater module to the air valve t\
hat each
cable operates. The cable ends are attach ed to the air valve crank arm by a
self-adjusting clip that grips the c able core firmly. Adjustment can be
accomplished by moving the mode lever (t o adjust the vent or defrost control
cables) or the temperature lever (to adjus t the temperature control cable) briskly
back and forth to both extremes of leve r travel in the control assembly. When
the cable is properly adjusted, the air va lve may be heard hitting it's stop at both
extremes of travel.

BLOWER SWITCH

With the control head removed from t
he vehicle, the blower switch may be
removed by pulling the blower switch knob off and removing the retaining clip or
retaining screws.

VACUUM MOTORS
OPERATION
Used on certain heating and air condition ing systems, the vacuum actuators
operate the air doors determining the differ ent modes. The actuator consists of
a spring loaded diaphragm connec ted to a lever. When vacuum is applied to the
diaphragm, the lever moves t he control door to its appropriate position. When
the lever on the control panel is moved to another position, vacuum is cut off
and the spring returns the actuator lever to its normal position.
TESTING 1. Disconnect the vacuum line from the actuator.
2. Attach a hand held vacuum pump to the actuator.
3. Apply vacuum to the actuator.
4. The actuator lever should move to its engaged position and remain there
while vacuum is applied.
5. When vacuum is released it should move back to its normal position.
6. The lever should operat e smoothly and not bind.
REMOVAL & INSTALLATION 1. Remove the vacuum li nes from the actuator.
2. Disconnect the linkage from the actuator.
3. Remove the hardware attaching the actuator.
4. Remove the actuator.
To install: 5. Install the actuator and attaching hardware.
6. Connect the linkage to the actuator.
7. Connect the vacuum lines to the actuator.
8. Test system to confirm proper functioning of the actuator.

ENGAGEMENT SWITCH
The engagement switch cannot be serviced . The complete multi-function lever
(turn signal lever) must be replaced as an assembly.
ADJUSTMENT
1. Depress the brake pedal and check that the release switch is fully seated
in the clips.
2. Slowly pull the brake pedal back to the at-rest position; the switch and
valve assembly will move within the clips to the adjusted position.
3. Measure pedal travel and check s witch engagement. The electric brake
release switch contacts must open at less than 1 inch (25.4 mm) of pedal
travel. The vacuum release should engage between
5/8 and 1 inch (16-
25mm) of pedal travel.
SERVO
REMOVAL & INSTALLATION 1. Disconnect the electrical connecto r and vacuum hoses at the servo.
2. Disconnect the actuating chain, cable or rod from the servo.
