14) Operate blower system to verify repair. If blower motor
operates normally, repair is complete. If blower motor is still
inoperative, return to step 2).
BLOWER MOTOR INOPERATIVE IN HIGH SPEED

1) Perform DIAGNOSTIC SYSTEM TEST. Go to next step.
2) Set mode switch in VENT position. Set blower motor switch
in highest speed position. Using test light connected to ground,
backprobe A/C-heater control panel harness connector C1 terminal "B"
(Orange 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 A1 (Orange wire). If test light
illuminates, go to step 6). If test light does not illuminate, go to
step 7).
4) Check for poor connection or connector damage at A/C-
heater control panel harness connector C1. See WIRING DIAGRAMS. Repair
or replace as necessary. After repair, go to step 13). If connections
are okay, go to next step.
5) Replace blower motor switch. See BLOWER MOTOR SWITCH under
REMOVAL & INSTALLATION. After repair, go to step 13).
6) Connect test light between blower motor relay harness
connector terminals A1 (Orange wire) and C2 (Black wire). If test
light illuminates, go to step 8). If test light does not illuminate,
go to step 9).
7) Repair open or poor connection in Orange wire between
blower motor relay harness connector terminal A1 and blower motor
resistor harness connector terminal "C". After repair, go to step 13).
8) Connect test light between blower motor relay harness
connector terminals A2 (Red wire) and C2 (Black wire). If test light
illuminates, go to step 10). If test light does not illuminate, go to
step 12).
9) Repair open or poor connection in Black wire between
blower motor relay harness connector terminal C2 and ground. After
repair, go to step 13).
10) Check for poor connections or connector damage at blower
motor relay harness connector. Repair or replace as necessary. After
repair, go to step 13). If connections are okay, go to next step.

1) Perform DIAGNOSTIC SYSTEM TEST. Go to next step.
2) Turn ignition switch to ON position. Set mode selector
switch to VENT position. Using test light connected to ground, probe
A/C-heater control panel harness connector C1 terminal "E" (Light
Green wire). If test light illuminates, go to next step. If test light
does not illuminate, go to step 15).
3) Set blower motor switch in low speed position. Using test
light connected to ground, probe A/C-heater control panel harness
connector C1 terminal "A" (Yellow wire). If test light illuminates, go
to next step. If test light does not illuminate, go to step 5).
4) Turn ignition switch to OFF position. Disconnect blower
motor relay. Connect fused jumper wire between blower motor relay
