Blower Motor Electrical Troubleshooting
To determine if an open condition exists within the blower motor circuit wiring, it is necessary to disconnect the neg-
ative battery cable and check for continuity within the blower motor circuits using an ohmmeter.
Possible causes of an inoperative blower motor include the following:
•Open fuse
• Inoperative blower motor switch
• Inoperative blower motor resistor
• Inoperative blower motor
• Inoperative blower motor circuit wiring or wiring harness electrical connectors
Blower Motor Noise
To determine if the blower motor is the source of the noise, simply switch the blower motor from Off to On. To verify
that the blower motor is the source of the noise, unplug the blower motor wire harness connector and operate the
heater-A/C system. If the noise goes away, possible causes include:
•Foreign material on fresh air inlet screen
• Foreign material in blower wheel
• Foreign material in HVAC housing
• Incorrect blower motor mounting
• Deformed or damaged blower wheel
• Worn blower motor bearings or brushes
Blower Motor Vibration
Possible causes of a blower motor vibration include:
•Incorrect blower motor mounting
• Foreign material in blower wheel
• Deformed or damaged blower wheel
• Worn blower motor bearings

1. Disconnect the negative battery cable.
2. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).
3. Remove the front bumper (See Front Bumper Removal & Installation in Section 15 Body & Accessories).
4. Remove the nut (3) that secures the A/C high-pres-sure liquid line to the A/C condenser. Remove and
discard the O-ring seal and gasket.
NOTE: After removing the A/C lines, plug the A/C
lines to prevent any debris from entering the A/C
system.
5. Remove the nut (2) that secures the A/C high-pres- sure gas line to the A/C condenser. Remove and
discard the O-ring seal and gasket.
6. Remove the condenser mounting bolts (1).
7. Remove the condenser from the engine compartment.
8. Installation is in the reverse order of removal.
Installation Notes:
• Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refriger-
ant line fittings.
• Use only the specified O-rings as they are made of a special material for the R-134a system.
• Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
• Recharge the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Condition-
ing).
Accumulator
Description
The accumulator is connected directly between the condenser and the expansion valve. Accumulator is used on sys-
tems that use an orifice tube to meter refrigerants into the evaporator.
Operation
The primary function of the accumulator is to isolate the compressor from any damaging liquid refrigerant. The accu-
mulator removes debris and moisture from the air conditioning system.
Removal & Installation
1. Disconnect the negative battery cable.
2. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).

Liquid Line
Description
The A/C liquid line connects the A/C condenser to the A/C evaporator.
Operation
The high pressure A/C liquid line is the refrigerant line that carries refrigerant from the A/C condenser to the A/C
accumulator. Air conditioning hoses are designed to control liquid and gas at high pressures and temperatures. The
hoses are usually flexible and equipped with special metal fittings at the ends to prevent leaks and provide a sure
seal and connection between components.
Removal & Installation
1. Disconnect the negative battery cable.
2. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).

The low pressure A/C suction line is the refrigerant line that carries refrigerant from the A/C accumulator to the A/C
compressor. Air conditioning hoses are designed to control liquid and gas at high pressures and temperatures. The
hoses are usually flexible and equipped with special metal fittings at the ends to prevent leaks and provide a sure
seal and connection between components.
Removal & Installation
1. Disconnect the negative battery cable.
2. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).

Battery
• Charge system
• Harness is open or
shorted
• RCM
DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the latest software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the RCM.
• Turn ignition switch off and wait for a few seconds.
• Turn ignition switch on then select view DTC.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 14 Restraints for more information).
Diagnostic Guide Lines
Observe the following guide lines while diagnosing this DTC:
•Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.
• If the warning lamp goes out immediately after the warning lamp flashed for6-7seconds, this indicates that
the system is OK.
• If the warning lamp is on for6-7seconds continuously, then goes out, or the warning lamp is on continuously,
this indicates that there are history DTCs in the system. Use the Scan Tool to erase the DTCs.
• If any other condition occurs, use the Scan Tool to erase the history DTCs first, then check the warning lamp.
If the warning lamp does not go out immediately after the warning lamp flashes for6-7seconds when using
the Scan Tool, erase the history DTCs first.
• In the course of troubleshooting the airbag system, make sure the system power supply is shut off, and wait
two minutes for the system capacitor to discharge.
• The squib circuit connectors integrate a shortingspring (which prevents the airbag from deploying unintention-
ally due to static electricity by shorting the positive wire to the negative wire in the squib circuit when the con-
nectors are disconnected). Therefore, if the airbag electrical connector or spiral cable electrical connector is
damaged or improperly connected, the shorting spring may not be released when the electrical connector is
connected.
• The following tools are required to perform the DTC diagnostic procedure:
X-431 Scan Tool
Airbag Special Load Tool
Digital Multimeter
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
