Chapter Review
The purpose of these brief inspection procedures is for vehicle system mainte-
nance and to determine if further, more detailed service is required. The uses of
a manifold gauge set, system troubleshooting, recovery, flushing, evacuating and
charging are explained in the next chapter.
High usage and operating condition variations are tough on air conditioning
and heater components. You should establish and follow regular inspection and
maintenance procedures to improve overall system function and component ser-
vice life.
The typical inspection should not take more than 15 to 20 minutes unless com-
ponent replacement and/or complete system evacuation and recharging is war-
ranted. The survey results shown in Figure 7-1, indicate belts, compressor clutch
assembly, condenser and the refrigerant lines are the most frequent problem ar-
eas. However, your own experience with service and maintenance may vary from
survey results.
Inspection should first be visual and by feel. Some of your electrical system
inspection will be done as you inspect other components (checking leads, connec-
tions and for loose wires). When you check the electrical circuit, begin with the
engine off but ignition on. A system performance inspection with the engine run-
ning and system on really combines electrical and AC or heater system function.
