A/C Gompressor Controls (conrd)
- How the Circuit Works
Battery voltage is supplied through fuse 56 to the
A,/C compressor clutch relay contacts at all times.
With the ignition switch in ON (ll), voltage is applied
to the coil of the A,/C compressor clutch relay
through fuse 17. When you push the A,/C switch
ON, and the heater fan switch is in posation 1, 2, 3,
or 4, a "ground" input is provided to the engine or
powertrain control module (ECM or PCM) through
the A,/C thermostat and the A,/C pressure switch.
The A,/C compressor clutch relay is grounded by the
engine or powertrain control module (ECM or PCM).
When energized, the A,/C compressor clutch relay
allows battery voltage to turn on the A,/C
comDressor clutch,
The A,/C ON indicator light comes on when the A"/C
system is requested.
A,/C Thermostat
The A,/C thermostat is located on the evaoorator
housing. The AJC thermostat turns off the A,/C
compressor clutch if the temperature at the
evaporator goes below 3'C (37'F). This prevents
condensation from freezing on the evaporator fins
and blocking the air delivery into the passenger
compartment. The blower motor will keep running
when the sensor lurns off the compressor.
A,/C Pressure Switch
The A,/C pressure switch is located in the condenser
outlet line where refrigerant is in a high
temperature/high pressure liquid state. The switch
will sense abnormally high or low pressure, and
open the circuit. This removes ground, and the
compressor will stop running.
Refer to the Service Manual (Section 22,
Air Conditioning) for specific tests or
troubleshooting procedures.

- How the Circuit Works
Voltage is applied at all times through f use 50 to
the rear window defogger relay. With the ignition
swrtch in ON (ll), voltage is applied through luse
16 to the rear window defogger relay and the
defogger ON indicator.
When you turn the rear window defogger switch to
ON, a path to ground is provided for the rear
window defogger relay and the defogger ON
indicator through the integrated control unit. The
defogger ON indicator light comes on and the rear
window detogger relay contacts close. Voltage is
applied to the detogger grid on the surface of the
rear window and the grid heats the rear window to
remove any fog lrom the glass.
A timer in the integrated control unit will automatically
tum off the defogger atter 20 to 30 minutes.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

- How the Circuit Works
The low engine oil pressure indicator light works in
two ways: il flashes continuously following a
momentary loss of engine oil pressure, or it comes
on and stays on with a complete loss of engine oil
oressure,
When the engine first starts, before its oil pressure
rises above 4.3 psi, voltage is applied to the closed
and grounded engine oil pressure switch and the
light comes on to test the bulb.
With the engine running, voltage is applied at the
WHT/BLU wire of the integrated control unit. With
normal engine oil pressure, the engine oil pressure
switch is open and the low oil pressure indicator
light does not come on. lf the engine oil pressure
switch closes momentarily (more than 0.5 seconds)
but then opens again, the YEURED wire at the
integrated control unit will sense ground through the
switch. The integrated control unit will then provide
and remove ground for the low oil pressure indicator
light through the YEURED wire. The light will flash
on and off until you turn the ignition switch off. The
flashing feature will not work until 30 seconds after
initial voltage is applied to the WHT/BLU wire of the
oil pressure indrcator llasher circuit. This delay
keeps the low oil pressure indicator light from
coming on during engine warm-up.
lf engine oil pressure falls below 4.3 psi and does
not increase, the engine oil pressure switch will stay
closed. The low oil pressure indicator light will then
come on and stay on.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
