14) Check Light Green wire between A/C-heater control panel
harness connector C2 terminal "B" and blower motor switch harness
connector C1 terminal "E" located at A/C-heater control panel for open
or high resistance. Repair Light Green wire as necessary. After
repair, go to step 24). If wire is okay, go to step 18).
15) Check for poor connections or connector damage at blower
motor relay harness connector. Repair or replace as necessary. After
repair, go to step 24). If connections are okay, go to step 20).
16) Check for poor connections or connector damage at blower
motor harness connector. Repair or replace as necessary. After repair,
go to step 24). If connections are okay, go to step 21).
17) Check for poor connections or connector damage at blower
motor resistor harness connector. Repair or replace as necessary.
After repair, go to step 24). If connections are okay, go to step 22).
18) Check for poor connections or connector damage at A/C-
heater control panel harness connectors. Repair or replace as
necessary. After repair, go to step 24). If connections are okay, go
to step 23).
19) Repair Red wire between blower motor relay harness
connector terminal A2 and I/P-1 fuse (40-amp) located in underhood
fuse block. After repair, go to step 24).
20) Replace blower motor relay. After repair, go to step 24).
21) Replace blower motor. See BLOWER MOTOR under REMOVAL &
INSTALLATION. After repair, go to step 24).
22) Replace blower motor resistor. See BLOWER MOTOR RESISTOR
under REMOVAL & INSTALLATION. After repair, go to step 24).
23) Replace A/C-heater control panel. See
A/C-HEATER CONTROL PANEL under REMOVAL & INSTALLATION. After repair,
go to next step.
24) Operate blower system to verify repair. If blower motor
operates normally, repair is complete. If blower motor is still
inoperative, return to step 2).
REMOVAL & INSTALLATION
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG SYSTEM SAFETY
article in GENERAL SERVICING.
A/C COMPRESSOR
Removal (3.8L Engine)
1) Disconnect negative battery cable from engine block ground
stud. Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Remove serpentine drive belt. Disconnect
electrical harness connector. Remove strap from compressor and
condenser hose assembly.
2) Raise and support vehicle. Remove compressor and condenser
hose bolt. Disconnect compressor and condenser hose assembly. Discard
"O" ring. Remove compressor bolts. Remove compressor and rear bracket
(if necessary).
Installation
1) To install, reverse removal procedure. If compressor is
being replaced, drain refrigerant oil from old compressor. Measure
amount of oil from old compressor. If measured amount is less than one
ounce, add 2 ounces to new compressor.
2) If more than one ounce is drained from old compressor, add
same amount to new compressor. Clean all fittings with mineral-base
refrigerant oil. Lightly coat all seals with mineral-base refrigerant
oil before assembling. Evacuate and charge A/C system.
