INSPECTION
ACTION
20
VERIFY THAT EXPANSION VALVE
HEAT-SENSING TUBE WITHIN COOLING UNIT
IS POSITIONED SECURELY AND CORRECTLY
• Is expansion valve heat-sensing tube within
cooling unit securely installed in proper
position?
Yes
Replace expansion valve, then go to next step.
(Since valve opens too much, replacement is
necessary.)
No
Install heat-sensing tube securely in proper
position, then go to next step.
21
CONFIRM THAT MALFUNCTION SYMPTOMS
DO NOT RECUR AFrER REPAIR
• Does cool air blow out? (Are results of
refrigerant system performance test okay?)
Yes
Troubleshooting completed. Explain repairs to
customer.
No
Recheck malfunction symptoms, then repeat from
Step 1 if malfunction recurs.
NO. 10 NO COOL AIR
10
No cool air.
DESCRIPTION
Magnetic clutch does not operate.
POSSIBLE
CAUSE
• A/C compressor system malfunction (Step 2)
• Incorrect amount of refrigerant (Step 3)
• A/C switch indicator light malfunction (Steps 4, 5)
• PCM A/C cut-off control system malfunction (Step 6)
• A/C relay malfunction (Step 8)
• Malfunctions in A/C amplifier and/or climate control unit (Steps 9-15)
• PCM (A/C signal) system malfunction (Steps 16, 17)
• Refrigerant pressure switch malfunction (Step 18)
• Malfunctions in PCM (IG1 signal) system and/or PCM condenser fan control system
(Steps 19-21)
• Malfunctions in magnetic clutch, magnetic clutch thermal protector and/or A/C relay (A/C control
signal) system (Steps 22-24)
Diagnostic procedure
• When performing an asterisked (*) troubleshooting inspection, shake the wiring harness and connectors while
doing the inspection to discover whether poor contact points are the cause of any intermittent malfunctions. If
there is a problem, check to make sure connectors, terminals and wiring harness are connected correctly and
undamaged.
STEP
INSPECTION
ACTION
1
INSPECT AIR BLOW OUT
• Does air blow out?
Yes
Go to next step.
No
Go to Step 1 of troubleshooting index NOs. 4, 5.
2
INSPECT A/C COMPRESSOR OPERATION
• Start engine.
• Turn both A/C switch and fan switch on.
• Does A/C compressor operate?
Yes
Go to Step 1 of troubleshooting index NO. 9.
No
Go to next step.
3
INSPECT REFRIGERANT AMOUNT
• Inspect refrigerant amount.
• Is it okay?
Yes
Go to next step.
No
Add or subtract refrigerant to specified level, then
go to Step 25.
4
INSPECT A/C SWITCH INDICATOR LIGHT
• Does A/C switch indicator light illuminate?
Yes
Go to Step 6.
No
Go to next step.
*5
CHECK TO SEE WHETHER MALFUNCTION
(LACK OF CONTINUITY) IS IN CLIMATE
CONTROL UNIT OR WIRING HARNESS
(BETWEEN CLIMATE CONTROL UNIT AND
RESISTOR)
• Turn ignition switch to ON position.
• Test voltage at climate control unit connector
(16-pin) terminal 2A (A/C signal).
• Is voltage approximately 12 V when fan
switch is off and 0 V when it is on?
Yes
Replace climate control unit, then go to Step 25.
No
Repair wiring harness between climate control
unit and resistor, then go to Step 25.
