Chapter Review
The purpose of these brief inspection procedures is for vehicle system maintenance
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 mainte-
nance procedures to improve overall system function and component service 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 warranted.
The survey results shown in Figure 7-1, indicate belts, compressor clutch assembly,
condenser and the refrigerant lines are the most frequent problem areas. 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 inspec-
tion will be done as you inspect other components (checking leads, connections 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 running and system on
really combines electrical and AC or heater system function.
