STEP
16 INSPECT DRIVE BELT CONDITION
• Is drive belt worn?
• Does it have foreign material imbedded in it,
or have oil on it?
17 INSPECT MAGNETIC CLUTCH
• Inspect magnetic clutch.
(See 07-40-7 MAGNETIC CLUTCH
INSPECTION.)
• Is it okay?
18 CHECK TO SEE WHETHER MALFUNCTION
IS IN A/C COMPRESSOR OR REFRIGERANT
LINES
• Is noise emitted from A/C compressor?
19 VERIFY THAT MALFUNCTION SYMPTOM
OCCURS AFTER REPAIR
• Has A/C compressor noise stopped?
* : If there is gas leakage, air enters into the A/C system. The desiccant within the receiver/drier absorbs the
moisture from the air and becomes saturated. If the A/C system is used in this condition, the inside of the A/C
compressor will begin to rust due to this moisture, which may cause lock up or noise to occur. Therefore,
replacement of the receiver/drier is necessary.
