switch in VENT position. Set blower motor switch in lowest speed

position. Using test light connected to ground, probe blower motor

resistor harness connector terminal "C" (Dark Blue wire). If test

light illuminates, go to next step. If test light does not illuminate,

go to step 4).

3) Using test light connected to ground, probe blower motor

relay harness connector terminal B2 (Dark Blue wire). If test light

illuminates, go to step 6). If test light does not illuminate, go to

step 8).

4) Check for poor connection or connector damage at blower

motor resistor harness connector. Repair or replace as necessary.

After repair, go to step 9). If connection is okay, go to next step.

5) Replace blower motor resistor. See BLOWER MOTOR RESISTOR

under REMOVAL & INSTALLATION. After repair, go to step 9).

6) Check for poor connection or connector damage at blower

motor relay harness connector. Repair or replace as necessary. After

repair, go to step 9). If connection is okay, go to next step.

7) Replace blower motor relay. After repair, go to step 9).

8) Repair open or poor connection in Dark Blue wire between

blower relay harness connector terminal B2 and blower motor resistor

harness connector terminal "C". After repair, go to next step.

9) Operate blower system to verify repair. If blower motor

operates normally, repair is complete. If blower motor is still

inoperative, return to step 3).

1) Perform DIAGNOSTIC SYSTEM TEST. Go to next step.

2) Turn ignition switch to OFF position. Disconnect blower

motor resistor harness connector. Turn ignition switch to ON position.

Set blower motor switch in OFF position. Using test light connected to

ground, probe A/C-heater control panel harness connector C1 terminal

for circuit corresponding to inoperative blower speed. See

WIRING DIAGRAMS. If test light illuminates on suspect circuit. go to

next step. If test light does not illuminate, go to step 5).

3) Check for poor connection or connector damage at blower

motor resistor harness connector. Repair or replace as necessary.

After repair, go to step 9). If connections are okay, go to next step.

4) Replace blower motor resistor. See BLOWER MOTOR RESISTOR

under REMOVAL & INSTALLATION. After repair, go to step 9).

5) Using test light connected to ground, individually probe

A/C-heater control panel harness connector C1 terminal which did not

cause test light to illuminate in step 2). If test light illuminates,

go to next step. If test light does not illuminate, go to step 7).

6) Repair open or poor connection in Yellow, Tan or Light

Blue wire(s) between A/C-heater control panel harness connector C1 and

blower motor resistor harness connector. See WIRING DIAGRAMS. After

repair, go to step 9).

7) Check for poor connections or connector damage at A/C-

heater control panel harness connector C1. Repair or replace as

necessary. After repair, go to step 9). If connections are okay, go to

next step.

8) Replace blower motor switch. See BLOWER MOTOR SWITCH under

REMOVAL & INSTALLATION. After repair, go to next step.

9) Operate blower system to verify repair. If blower motor

operates normally, repair is complete. If blower motor is still

inoperative, return to step 3).
