HIGH PRESSURE SWITCH
The high pressure switch, installed in refrigerant line, is
wired in series with compressor clutch. When refrigerant pressures
rise above switch control pressure point, power to compressor clutch
is cut. The high pressure switch may also be activated when airflow
through condenser is blocked or when system is overcharged.
HIGH/LOW PRESSURE CUT-OFF SWITCH
The High/Low Pressure Cut-Off (HLPCO) switch, located on
refrigerant line, is wired in series with compressor clutch. Switch
cuts off power to compressor clutch when refrigerant pressures are
above or below switch control point. When pressure returns to normal
operating range, compressor clutch operation resumes.
LOW PRESSURE SWITCH
The low pressure switch, located in receiver-drier, is wired
in series with compressor clutch. When refrigerant pressure drops
below switch control point (usually due to leak in system), power to
compressor clutch is cut.
REFRIGERANT TEMPERATURE SWITCH
The refrigerant temperature switch, located on rear of
compressor, detects refrigerant temperature discharged from
compressor. A/C Control Unit (ACCU) uses this information to control
compressor clutch cycling.
ADJUSTMENTS

MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection communication standards
