DESCRIPTION AND OPERATION
AIR CONDITIONING-HEATER SYSTEM
The A/C-Heater System is powered by a by several
fuses. Fuse 10, a 15 amp fuse located in the fuse
block, is HOT in the RUN position. This fuse powers
the coil side of the A/C compressor clutch relay
located in the Power Distribution Center (PDC).
A 30 amp fuse, on circuit A16 located in the PDC,
powers the solid state radiator fan relay. This fuse is
HOT at all times. The 10 amp fuse on circuit A17
located in the PDC powers the contact side of the A/C
compressor clutch relay.
The A/C-Heater blower motor is protected by a 25
amp fuse located in cavity 7 of the fuse block. This
fuse in HOT in the RUN position only. When the
ignition switch is in the RUN position, power is sup-
plied to the fuse on circuit A22. The power leaves the
fuse on circuit C1 and goes directly to the blower
motor.
There is a 4 amp fuse located in cavity 12 of the
fuse block used for the illumination lamps in the A/C-
Heater control. The fuse is HOT at all times.
A/C OPERATION
When the A/C or the defrost switch is put in the
ON position, and the A/C cycling switch, low pressure
cut-out switch, and the high pressure switch are
CLOSED, the Powertrain Control Module (PCM)
receives a request for A/C.
After receiving this input, the PCM activates the
A/C compressor by grounding the C28 circuit on the
coil side of the A/C Compressor Clutch relay. Power
for the coil side of the relay is supplied on the bus
bar located in the Power Distribution Center (PDC).
With the coil energized, current flows from the 10
amp fuse in the PDC on circuit A17 through the
CLOSED contacts in the relay, on the C3 circuit to
the A/C compressor clutch.
The A/C compressor clutch receives this voltage
and creates a magnetic field energizing the clutch.
Ground for the coil is provided at the right headlamp
ground.
The connector at the A/C compressor has a diode
located in it. This diode is used to control the inducedvoltage resulting from the magnetic field collapsing
when the clutch is disengaged. The diode provides a
path for the voltage to protect other components and
systems.
The A/C compressor clutch relay is also used by the
PCM to disengage the compressor in a Wide Open
Throttle (W.O.T.) condition.
RADIATOR FAN OPERATION
The radiator fan system used in this vehicle uses a
solid state relay that controls the speed of the radia-
tor fan.
Power for the relay is supplied on circuit A16 This
circuit is HOT at all times and protected by a 30 amp
fuse located in the Power Distribution Center (PDC).
Ground for the coil side of the relay is controlled by
the Powertrain Control Module (PCM). When the
PCM determines the need for fan operation the PCM
supplies the ground path for circuit K173. This cir-
cuit connects to cavity 18 of the PCM connector.
From the relay circuit C25 connects to the radiator
fan motor(s). On vehicles equipped with the manual
transmission only one radiator fan is used. For vehi-
cles equipped with an automatic transmission there
are two radiator fans used.
Ground for the radiator fans is supplied on circuit
Z1.
BLOWER MOTOR OPERATION
With the ignition switch in the RUN position,
power flows from the 25 amp fuse, in cavity 7 of the
fuse block, to the blower motor. Blower motor speed
is controlled by the fan control switch located in the
instrument panel, and the resistor block.
Blower motor LOW speed operation is accom-
plished on the C4 circuit. When the control switch is
moved to the LOW speed position, current is passed
on the C7 circuit through the blower motor resistor
to the C4 circuit. It then flows through the blower
motor switch to the Z8 circuit. The Z8 circuit termi-
nates at a grounding point on the instrument panel
left center support.
The operation of the blower motor M1 and M2
speed operations is the same as the LOW speed
8W - 42 - 6 8W - 42 AIR CONDITIONING-HEATERPL
Page 113 of 256
Downloaded from www.Manualslib.com manuals search engine except, the C5 circuit is used for the M1 speed and
circuit C6 is used for M2 speed operation.
Blower motor HIGH speed operation is accom-
plished on the C7 circuit which supplies battery volt-
age directly to the blower motor. There are no
resistors used in the HIGH speed mode.
HELPFUL INFORMATION
²Check the 30 amp fuse located in the PDC for
the radiator fan motor
²Check the 15 amp fuse located in cavity 10 of
the fuse block for the A/C compressor clutch relay
²Check the 10 amp fuse located in the PDC for
the A/C compressor clutch relay.
²Check the 25 amp fuse located in cavity 7 of the
fuse block for the blower motor.
²Check the right headlamp ground located at the
right fender side shield.
²Check the left headlamp ground located on the
left side of the radiator closure panel.
²On vehicles equipped with A/C check the refrig-
erant level. The system will not operate with a low
level of refrigerant.

DESCRIPTION AND OPERATION
HELPFUL INFORMATION.................. 3POWER WINDOWS...................... 3
DESCRIPTION AND OPERATION
POWER WINDOWS
The power window system is supplied power from
the 30 amp circuit breaker located behind the fuse
block. Power for the circuit breaker is supplied on
circuit A22 from the ignition switch. This circuit is
HOT when the ignition switch is in the RUN posi-
tion.
Power for the A22 circuit is supplied by the A2 cir-
cuit which is HOT at all times and protected by a
40-amp fuse located in the Power Distribution Center
(PDC). The A22 is spliced and supplies power for the
fuses that protect the Airbag, A/C-Heater blower
motor, turn signals, and the heated rear window.
Circuit F21 connects, from the circuit breaker, to
both window switches. This is the feed for the
switches. Both switches use a BUS bar to provide
power for the different functions of the switch.
The ground path for the system is through master
window switch on the Z8 circuit. The grounding point
is located at the instrument panel left center support
brace.
MASTER WINDOW SWITCH (LEFT WINDOW
OPERATION)
When the window switch is moved to the window
DOWN position, voltage is supplied on the F21 cir-
cuit through the CLOSED contacts in the switch to
the Q21 circuit. The Q21 circuit connects from the
switch to the left front window motor. Grounding is
provided on circuit Q11 from the motor back to the
switch. The ground is passed through the switch to
the Z8 circuit. The Z8 circuit goes to its grounding
point.
When window UP operation is selected, the power
and ground circuits are reversed. Circuit Q11 is the
feed and circuit Q21 is the ground.
MASTER WINDOW SWITCH (RIGHT WINDOW
OPERATION)
When the window switch is moved to the window
DOWN position, voltage is supplied on the F21 cir-
cuit through the CLOSED contacts in the switch to
the Q26 circuit. The Q26 circuit connects from the
master switch to the right window switch. A BUS barinternal to the right switch passes the voltage
through the switch to circuit Q22. Circuit Q22 con-
nects from the switch to the right window motor.
Grounding is provided on circuit Q12 from the motor
back to the right switch.
The ground is passed through the switch on a BUS
bar to circuit Q16. Circuit Q16 then goes to the mas-
ter switch. The ground is passed through the switch
to the Z8 circuit. The Z8 circuit attaches to its
grounding point.
When window UP operation is selected, the power
and ground circuits are reversed. Circuits Q12 and
Q16 are the feeds and circuits Q22 and Q26 are the
grounds.
RIGHT WINDOW SWITCH OPERATION
When the window switch is moved to the window
DOWN position, voltage is supplied on the F21 cir-
cuit through the CLOSED contacts in the switch to
the Q22 circuit. The Q22 circuit connects from the
switch to the right front window motor. Grounding is
provided on circuit Q12 from the motor back to the
switch. The ground is passed through the switch to
the Q16 circuit. The Q16 circuit connects from the
right switch to the master switch. Ground is passed
through the master switch to the Z8 circuit. The Z8
circuit goes to its grounding point.
When window UP operation is selected, the power
and ground circuits are reversed. Circuit Q12 is the
feed and circuit Q22 is the ground.
HELPFUL INFORMATION
²Check the 40 amp fuse located in the PDC.
²Check the 30 amp circuit breaker located behind
the fuse block.
²Check the ground at the instrument panel left
center support.
