AUTO A/C DIAGNOSIS
INTRODUCTIONM1554006200062
After air is taken in through the damper, it is fed to
the evaporator by the blower fan and motor and
cooled. The air cooled by the air mix damper is
mixed appropriately with the warmed air to achieve a
comfortable temperature. If the A/C does not operate
or the cooled air is not discharged, the system com-
ponents or relay may be faulty.
AUTOMATIC AIR CONDITIONING TROUBLESHOOTING STRATEGYM1554004700157
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a
heater, air conditioning and ventilation fault.
1. Gather information from the customer.2. Verify that the condition described by the
customer exists.
3. Find the malfunction by following the Symptom
Chart.
4. Verify malfunction is eliminated.
