3. CHARGE REFRIGERANT INTO REFRIGERANT SYS-
TEM
If there is no leak after refrigerant leak check, charge the proper
amount of refrigerant into refrigeration system.
CAUTION:

Never run the engine when charging the system
through the high pressure side.

Do not open the low pressure hand valve when the
system is being charged with liquid refrigerant.
(a) Open the high pressure hand valve fully.
(b) Charge specified amount of refrigerant, then close the
high pressure hand valve.
HINT:
A fully charged system is indicated by the sight glass being free
of any bubbles.
(c) Charge partially refrigeration system with refrigerant.
(1) Set vehicle in these conditions:

Running engine at 1,500 rpm

Blower speed control set at ºHIº

Temperature control set at ºMAX. COOLº

Air inlet control set at ºRECIRCº

Fully open doors (Sliding roof: closed)
(2) Open the low pressure hand valve.
CAUTION:
Do not open the high pressure hand valve.
(d) Charge refrigerant until bubbles disappear and check the
pressure on the gauge through the sight glass.

2. INSPECT DOME LAMP SWITCH
(a) Disconnect the connector from the dome lamp.
(b) Turn the dome lamp switch ON, check that continuity ex-
ists between terminal 2 and body ground.
(c) Turn the dome lamp switch DOOR, check that there is
continuity exists between terminal 1 and 2.
If operation is not as specified, replace the switch.
3. INSPECT DOOR COURTESY SWITCH CONTINUITY
(a) Check that continuity exists between terminal and the
switch body with the switch ON (switch pin released:
opened door).
(b) Check that no continuity exists between terminal and the
switch body with the switch OFF (switch pin pushed in:
closed doors).
If operation is not as specified, replace the switch.

2. INSPECT SLIDING ROOF MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (±) lead to terminal 1, check that the
motor turns counterclockwise (moves to the close and up
side).
(b) Reverse the polarity, check that the motor turns clockwise
(moves to the open and down side).
If operation is not as specified, replace the motor.
3. INSPECT CIRCUIT BREAKER OPERATION
(a) With the sliding roof in the fully opened position, hold the
sliding roof switch in ºOPENº position and check that is a
circuit breaker operation noise is heard within 10 to 60 se-
conds.
